Continuing our work to gradually plumb context.Context to everywhere that
we want to generate OpenTelemetry traces, this completes the call path
for most (but not all) of the gRPC requests to provider plugins, so that
we can add OpenTelemetry trace instrumentation in a future commit.
Unfortunately there are still a few providers.Interface callers left in
functions that don't have context.Context plumbed to them yet, and so
those are temporarily stubbed as context.TODO() here so we can more easily
find and complete them later.
The two gRPC implementations of providers.Interface were previously making
provider requests using a single context.Context established at the time
the provider process was started, but that isn't an appropriate context
to use for per-request concerns like tracing, so that context is now
unused and could potentially be removed in a future commit, but this change
already got pretty large and so I intend to deal with that separately
later.
This now exposes the gRPC provider calls to potential context cancellation
that they would previously observe only indirectly though the Stop method.
Since Stop is primarily used for graceful shutdown of ApplyResourceChange,
the changes here explicitly disconnect the cancellation signal for
ApplyResourceChange in particular, while letting the others get canceled
in the normal way since they are expected to be free of significant
side-effects. In future work we could consider removing Stop from the
internal API entirely and keeping it only as an implementation detail of
the gRPC implementation of this interface, with ApplyResourceChange
directly reacting to context cancellation and sending the gRPC Stop call
itself, but again that's too much change for this already-large commit.
The internal/legacy package currently contains some legacy code preserved
for the benefit of the backends, and unfortunately contains more than is
strictly necessary to support those callers, and so there was some dead
code there that also needed updating. provider_mock.go is removed entirely
because it's just an older copy of the similar file in package tofu. The
few calls to providers in schemas.go are updated to use
context.Background() rather than context.TODO() because we have no
intention of plumbing context.Context into that legacy code, and will
hopefully just delete it wholesale one day.

Go 1.24 introduces stricter checks for format string validation.
This commit fixes instances where non-constant format strings were
used in calls to functions like `fmt.Errorf`, `fmt.Printf`, and similar.
Changes include:
- Replacing dynamically constructed strings passed as format strings
with constant format strings.
- Refactoring `fmt.Sprintf` calls to ensure the format string matches
the number of arguments provided.
- Simplifying redundant formatting and ensuring compliance with Go
1.24's stricter `vet` tool checks.
This update ensures compatibility with Go 1.24 and prevents potential
runtime errors caused by misinterpreted dynamic format strings.
Resolves#2389

Allow core to always use the global schema cache, so that providers
without GetProviderSchemaOptional are not spun up repeatedly. Rather
than conditionally setting the cache, we just conditionally use the
cache in the client to work around providers without
GetProviderSchemaOptional.
Add a single global schema cache for providers. This allows multiple
provider instances to share a single copy of the schema, and prevents
loading the schema multiple times for a given provider type during a
single command.
This does not currently work with some provider releases, which are
using GetProviderSchema to trigger certain initializations. A new server
capability will be introduced to trigger reloading their schemas, but
not store duplicate results.
This is most easily handled in the plugin code, without involving
Terraform core.
The biggest change here other than checking the PlanDestroy capability,
is the removal of the schema helper methods in the plugins. With the
addition of the capabilities field, combined with the necessity of
checking diagnostics from the schema, the helpers have outlived their
usefulness. Perhaps there's a better pattern for these repetitive calls,
but for now there isn't too extra verbosity involved.
We can no longer be assured that the particular instance of a provider
we are using has had GetProviderSchema called. Always check the
diagnostics even if we're fetching a cached response.
This is part of a general effort to move all of Terraform's non-library
package surface under internal in order to reinforce that these are for
internal use within Terraform only.
If you were previously importing packages under this prefix into an
external codebase, you could pin to an earlier release tag as an interim
solution until you've make a plan to achieve the same functionality some
other way.
