Part of the upgrade process happens in the first "terraform apply" after
adding explicit source addresses in the configuration. Previously we just
left that implied under the assumption that everyone would run
"terraform apply" shortly after anyway, but there is a specific tricky
situation where the first change after upgrading is to remove a resource
from the configuration, leaving Terraform unable to complete the upgrade.
Because of that, we'll now explicitly direct users to run
"terraform apply" after upgrading. Along with that, there's a reminder to
make sure that "terraform plan" indicates no changes before upgrading, so
that completing the upgrade doesn't involve also applying changes to
remote objects.

* command/init: return an error with invalid -backend-config files
The -backend-config flag expects a set of key-value pairs or a file
containing key-value pairs. If the file instead contains a full backend
configuration block, it was silently ignored. This commit adds a check
for blocks in the file and returns an error if they are encountered.

Although this command is removed in Terraform 0.13, our documentation is
for all versions of Terraform that remain in common use and keeping this
documented will be helpful for folks who are still using Terraform 0.11
and planning their upgrades to Terraform 0.12.
Both of the upgrade commands now include notes that they are only
available in their specific major version, along with a link to the
relevant upgrade guide for other background information about the upgrade,
in case the user finds the command documentation first. (The command docs
are, I think, a little more discoverable than the upgrade guides.)
We previously covered everything about using providers on a single page,
but that was getting unwieldy already and we now have a lot more to
discuss with v0.13 introducing a new source address syntax and some other
concepts.
Here we split the provider-related content into two parts: "Provider
Requirements" covers how to find and declare dependencies on providers,
and then "Provider Configuration" (formerly just "Providers") then focuses
primarily on how to write zero or more provider configurations for a
particular provider.
Because "Provider Requirements" is now presented before "Provider
Configuration" in the navigation, I've also moved some of the introductory
content about providers in general onto the "Requirements" page. The
first paragraph of that content is duplicated onto the "Configuration"
page for discoverability, but we now link to the requirements page to get
the full story.
The "Configuration Language" section was becoming rather unweildy, both
by having a lot of pages and by some of the pages being quite large in
themselves.
This is a first step towards breaking things up a little more, starting
with two changes:
- The "Configuration Language" navigation is now split into two
sub-headings "Configuration Blocks" and "Syntax".
- Some of the information about sub-blocks of the "terraform" block are
now given their own pages, because their content is quite complex
in itself.
- "Version Constraints" is now a page in its own right, rather than this
content being duplicated in slightly different forms across multiple
contexts that make use of user-specified version constraints.
We previously had the module registry protocol documented only as an
undefined subset of the full API of the official registry implementation.
However, the vast majority of endpoints documented in the official API
docs are not needed for a headless third-party module registry that only
intends to make modules available to Terraform CLI.
To make this clearer to potential third-party implementors, and also for
consistency with how the provider registry protocol is now documented,
here we create a new page to describe the subset required for all
registries, and then explain in the docs for the offical API that
potential third-party implementors should refer to the new page instead.
The longer page describing the full API of the official implementations
remains for those who wish to write clients for that API, because it is
part of the API surface area for Terraform Cloud and Terraform Enterprise.
I also took this opportunity to address the fact that module addresses
don't really contain "provider names" at all, but rather than the fourth
field in the address is _conventionally_ an official provider name but
can really be any string that serves to differentiate multiple
implementations of the same abstraction. The new docs therefore refer to
this field as "system" rather than "provider".
