Alisdair McDiarmid fc7e467d19 command: Add redirect support to 0.13upgrade
If a provider changes namespace in the registry, we can detect this when
running the 0.13upgrade command. As long as there is a version matching
the user's constraints, we now use the provider's new source address.
Otherwise, warn the user that the provider has moved and a version
upgrade is necessary to move to it.

Martin Atkins 2bd2a9a923 internal/getproviders: HTTPMirrorSource implementation
We previously had this just stubbed out because it was a stretch goal for
the v0.13.0 release and it ultimately didn't make it in.

Here we fill out the existing stub -- with a minor change to its interface
so it can access credentials -- with a client implementation that is
compatible with the directory structure produced by the
"terraform providers mirror" subcommand, were the result to be published
on a static file server.

internal/getproviders: decode and return any registry warnings (#25337)
* internal/getproviders: decode and return any registry warnings

The public registry may include a list of warnings in the "versions"
response for any given provider. This PR adds support for warnings from
the registry and an installer event to return those warnings to the
user.

Alisdair McDiarmid e27a36cafd internal/getproviders: Retry failed HTTP requests
This is a port of the retry/timeout logic added in #24260 and #24259,
using the same environment variables to configure the retry and timeout
settings.

getproviders: move protocol compatibility functions into registry client (#24846)
* internal/registry source: return error if requested provider version protocols are not supported

* getproviders: move responsibility for protocol compatibility checks into the registry client

The original implementation had the providercache checking the provider
metadata for protocol compatibility, but this is only relevant for the
registry source so it made more sense to move the logic into
getproviders.

This also addresses an issue where we were pulling the metadata for
every provider version until we found one that was supported. I've
extended the registry client to unmarshal the protocols in
`ProviderVersions` so we can filter through that list, instead of
pulling each version's metadata.

Alisdair McDiarmid 62b0cbed12 internal: Fix LookupLegacyProvider
When looking up the namespace for a legacy provider source, we need to
use the /v1/providers/-/{name}/versions endpoint. For non-HashiCorp
providers, the /v1/providers/-/{name} endpoint returns a 404.

This commit updates the LegacyProviderDefaultNamespace method and the
mock registry servers accordingly.

Alisdair McDiarmid a5b3d497cc internal: Verify provider signatures on install
Providers installed from the registry are accompanied by a list of
checksums (the "SHA256SUMS" file), which is cryptographically signed to
allow package authentication. The process of verifying this has multiple
steps:

- First we must verify that the SHA256 hash of the package archive
  matches the expected hash. This could be done for local installations
  too, in the future.
- Next we ensure that the expected hash returned as part of the registry
  API response matches an entry in the checksum list.
- Finally we verify the cryptographic signature of the checksum list,
  using the public keys provided by the registry.

Each of these steps is implemented as a separate PackageAuthentication
type. The local archive installation mechanism uses only the archive
checksum authenticator, and the HTTP installation uses all three in the
order given.

The package authentication system now also returns a result value, which
is used by command/init to display the result of the authentication
process.

There are three tiers of signature, each of which is presented
differently to the user:

- Signatures from the embedded HashiCorp public key indicate that the
  provider is officially supported by HashiCorp;
- If the signing key is not from HashiCorp, it may have an associated
  trust signature, which indicates that the provider is from one of
  HashiCorp's trusted partners;
- Otherwise, if the signature is valid, this is a community provider.

Martin Atkins 4d7122a0dd internal/getproviders: LookupLegacyProvider
This is a temporary helper so that we can potentially ship the new
provider installer without making a breaking change by relying on the
old default namespace lookup API on the default registry to find a proper
FQN for a legacy provider provider address during installation.

If it's given a non-legacy provider address then it just returns the given
address verbatim, so any codepath using it will also correctly handle
explicit full provider addresses. This also means it will automatically
self-disable once we stop using addrs.NewLegacyProvider in the config
loader, because there will therefore no longer be any legacy provider
addresses in the config to resolve. (They'll be "default" provider
addresses instead, assumed to be under registry.terraform.io/hashicorp/* )

It's not decided yet whether we will actually introduce the new provider
in a minor release, but even if we don't this API function will likely be
useful for a hypothetical automatic upgrade tool to introduce explicit
full provider addresses into existing modules that currently rely on
the equivalent to this lookup in the current provider installer.

This is dead code for now, but my intent is that it would either be called
as part of new provider installation to produce an address suitable to
pass to Source.AvailableVersions, or it would be called from the
aforementioned hypothetical upgrade tool.

Whatever happens, these functions can be removed no later than one whole
major release after the new provider installer is introduced, when
everyone's had the opportunity to update their legacy unqualified
addresses.

Martin Atkins a77bc59c44 internal/getproviders: Package URL should always be absolute
Registries backed by static files are likely to use relative paths to
their archives for simplicity's sake, but we'll normalize them to be
absolute before returning because the caller wouldn't otherwise know what
to resolve the URLs relative to.

Martin Atkins c76260e957 internal/getproviders: Query a provider registry
Our existing provider installer was originally built to work with
releases.hashicorp.com and later retrofitted to talk to the official
Terraform Registry. It also assumes a flat namespace of providers.

We're starting a new one here, copying and adapting code from the old one
as necessary, so that we can build out this new API while retaining all
of the existing functionality and then cut over to this new implementation
in a later step.

Here we're creating a foundational component for the new installer, which
is a mechanism to query for the available versions and download locations
of a particular provider.

Subsequent commits in this package will introduce other Source
implementations for installing from network and filesystem mirrors.
