We previously used a loader -> BuildConfig flow to load configuration.
This commit changes most (but not all yet) flows to use the new
graph-based approach. Instead of simply recursively loading the modules,
we now need to take a stepped approach:
1. Load the root module
2. Collect the variables and their values
3. Build the configuration with the graph-based approach
Because this approach relies on different parts from different packages,
it can't easliy be done within the `configload` package. So, now we do
most of in the backend or command.
This prevents a cyclic dependency and also makes sense semantically.
The arguments package will collect the unparsed variable values and
the backendrun helpers will work to collect the values and transform
them into terraform.InputValue.
* chore: Upgrade golang.org/x/crypto - `go get golang.org/x/crypto@v0.44.0`
* chore: Upgrade golang.org/x/crypto in submodules - `make syncdeps`
* chore: Run `make generate`
* chore: Ignore SA4003 linter error globally, as `golang.org/x/tools/cmd/stringer` generates code that breaks this rule when it's used with custom types that have unsigned integers or bytes as the underlying type.
* Update call to StateMgr method to use diagnostics more explicitly
* Update calling code in remote backend tests
* Update calling code in non-test code to handle diags conventionally.
* Fix test failure messages from using wrong variable
* Additional refactoring
* Add ability to parse backend blocks present in a test file's run blocks, validate configuration (#36541)
* Add ability to parse backend blocks from a run block

* Correct local backend blocks in new test fixtures
* Add test to show that different test files can use same backend block for same state key.
* Add validation to enforce state-storage backend types are used
* Remove TODO comment
We only need to consider one file at a time when checking if a state_key already has a backend associated with it; parallelism in `terraform test` is scoped down to individual files.
* Add validation to assert that the backend block must be in the first apply command for an internal state
* Consolidate backend block validation inside a single if statement
* Add initial version of validation that ensures a backend isn't re-used within a file
* Explicitly set the state_key at the point of parsing the config
TODO: What should be done with method (moduletest.Run).GetStateKey?
* Update test fixture now that reusing backend configs has been made invalid

* Fix rebase
* Change to accessing backend init functions via ContextOpts
* Add tests demonstrating how runs containing backend blocks use and update persisted state
* Fix test fixture
* Address test failure due to trouble opening the state file
This problem doesn't happen on MacOS, so I assume is due to the Linux environment of GitHub runners.
* Fix issue with paths properly
I hope
* Fix defect in test assertion
* Pivot back to approach introduced in 4afc3d7
* Let failing tests write to persistent state, add test case covering that.
I split the acceptance tests into happy/unhappy paths for this, which required some of the helper functions' declarations to be raised up to package-level.
* Change how we update internal state files, so that information about the associated backend is never lost
* Fix UpdateStateFile
* Ensure that the states map set by TestStateTransformer associates a backend with the correct run.

This implementation is very barebones, but builds the skelleton for
all upcoming features in actions. It includes the graph implementation
for planning actions including the expansion of actions and dealing
with multiple action triggers.
We plan all actions as part of their triggering resource for now.
All action_triggers depend on the triggering resources plan to
determine if an action should run or not, therefore we can plan
the actions as part of the triggering resource.
This implementation ignores conditions, deferrals, provider arguments
and it does not add the actions to the planfile; mostly to enable more
people to work on these issues in parallel.
* terraform test: add variable definitions to test files
Currently, `terraform test` attempts to work out the type of any external variables by delaying evaluation until each run block executes so it can use the definitions within the run blocks's module. This means that the values of variables can technically change between run blocks which isn't ideal.
This commit is the first in a chain which will move the evaluation of variables into the terraform test graph. We need to give the users the option of specifying the type for external variables within the file as these variables are now going to be assessed outside of the context of a run block. To do this, we introduce the optional variable blocks that are added by this commit.
* update comment
* terraform test: refactor the context initialisation into specific node in the graph
