The new config loader requires some steps to happen in a different
order, particularly in regard to knowing the schema in order to
decode the configuration.
Here we lean directly on the configschema package, rather than
on helper/schema.Backend as before, because it's generally
sufficient for our needs here and this prepares us for the
helper/schema package later moving out into its own repository
to seed a "plugin SDK".
S3 accepts objects with a leading slash and strips them off. This works
fine except in our workspace hierarchy, which then can no longer find
suffixes matching the full key name.
Since the DynamoDB table used by the S3 backend is no longer only used
for locks, rename it in the config to remove any confusion about it
being lock-specific.
Prevent extra keys in the s3 envPrefix path from showing up as
listed environments.
Better handle keys containing slashes
Add tests for unexpected keys in s3.
Use the aws provider code to create the clients for the s3 backend, so
that all the behavior matches that of the provider.
Remove the fake creds from the test, as the aws provider will attempt to
validate them.
This adds named state (environment) support to the S3 backend.
A state NAME will prepend the configured s3 key with `env:/NAME/`.
The default state will remain rooted in the bucket for backwards
compatibility.
Locks in DynamoDB use the S3 key as the as the primary key value, so
locking will work as expected for multiple states.
Move the S3 State from a legacy remote state to an official backend.
This increases test coverage, uses a set schema for configuration, and
will allow new backend features to be implemented for the S3 state, e.g.
"environments".
