* terraform: add helper functions for creating test state
testSetResourceInstanceCurrent and testSetResourceInstanceTainted are
wrapper functions around states.Module.SetResourceInstanceCurrent()
used to set a resource in state. They work with current, non-deposed
resources with no dependencies.
testSetResourceInstanceDeposed can be used to set a desosed resource in state.
* terraform: update all tests to use modern providers and state
a large refactor to addrs.AbsProviderConfig, embedding the addrs.Provider instead of a Type string. I've added and updated tests, added some Legacy functions to support older state formats and shims, and added a normalization step when reading v4 (current) state files (not the added tests under states/statefile/roundtrip which work with both current and legacy-style AbsProviderConfig strings).
The remaining 'fixme' and 'todo' comments are mostly going to be addressed in a subsequent PR and involve looking up a given local provider config's FQN. This is fine for now as we are only working with default assumption.
Previously we had a bug where we'd use the resource type name instead of
the provider name. Now we use the DefaultProviderConfig helper function
to extract the provider name from the resource type name.
After the refactoring to integrate HCL2 many of the tests were no longer
using correct types, attribute names, etc.
This is a bulk update of all of the tests to make them compile again, with
minimal changes otherwise. Although the tests now compile, many of them
do not yet pass. The tests will be gradually repaired in subsequent
commits, as we continue to complete the refactoring and retrofit work.
