This completes some of the missing connections for contexts in the provider
source codepaths by introducing context.Context parameters and wiring them
through so we can eliminate a few more context.TODO() placeholders.
For consistency's sake this adds context.Context to all four of the
getproviders.Source implementations that directly interact with stuff
outside of OpenTofu (network services or filesystem), even though not
all of them currently make use of it, just because interactions with
outside stuff tends to encourage cross-cutting concerns like logging and
tracing and so this ensures we have contexts propagated in there for such
future uses.

The primary reason for this change is that registry.NewClient was
originally imposing its own decision about service discovery request
policy on every other user of the shared disco.Disco object by modifying
it directly.
We have been moving towards using a dependency inversion style where
package main is responsible for deciding how everything should be
configured based on global CLI arguments, environment variables, and the
CLI configuration, and so this commit moves to using that model for the
HTTP clients used by the module and provider registry client code.
This also makes explicit what was previously hidden away: that all service
discovery requests are made using the same HTTP client policy as for
requests to module registries, even if the service being discovered is not
a registry. This doesn't seem to have been the intention of the code as
previously written, but was still its ultimate effect: there is only one
disco.Disco object shared across all discovery callers and so changing its
configuration in any way changes it for everyone.
This initial rework is certainly not perfect: these components were not
originally designed to work in this way and there are lots of existing
test cases relying on them working the old way, and so this is a compromise
to get the behavior we now need (using consistent HTTP client settings
across all callers) without disrupting too much existing code.

Several times over the years we've considered adding tracing
instrumentation to Terraform, since even when running in isolation as a
CLI program it has a "distributed system-like" structure, with lots of
concurrent internal work and also some work delegated to provider plugins
that are essentially temporarily-running microservices.
However, it's always felt a bit overwhelming to do it because much of
Terraform predates the Go context.Context idiom and so it's tough to get
a clean chain of context.Context values all the way down the stack without
disturbing a lot of existing APIs.
This commit aims to just get that process started by establishing how a
context can propagate from "package main" into the command package,
focusing initially on "terraform init" and some other commands that share
some underlying functions with that command.
OpenTelemetry has emerged as a de-facto industry standard and so this uses
its API directly, without any attempt to hide it behind an abstraction.
The OpenTelemetry API is itself already an adapter layer, so we should be
able to swap in any backend that uses comparable concepts. For now we just
discard the tracing reports by default, and allow users to opt in to
delivering traces over OTLP by setting an environment variable when
running Terraform (the environment variable was established in an earlier
commit, so this commit builds on that.)
When tracing collection is enabled, every Terraform CLI run will generate
at least one overall span representing the command that was run. Some
commands might also create child spans, but most currently do not.
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.
