Martin Atkins 0b734a2803 command: Make provider installation interruptible
In earlier commits we started to make the installation codepath
context-aware so that it could be canceled in the event of a SIGINT, but
we didn't complete wiring that through the API of the getproviders
package.

Here we make the getproviders.Source interface methods, along with some
other functions that can make network requests, take a context.Context
argument and act appropriately if that context is cancelled.

The main providercache.Installer.EnsureProviderVersions method now also
has some context-awareness so that it can abort its work early if its
context reports any sort of error. That avoids waiting for the process
to wind through all of the remaining iterations of the various loops,
logging each request failure separately, and instead returns just
a single aggregate "canceled" error.

We can then set things up in the "terraform init" and
"terraform providers mirror" commands so that the context will be
cancelled if we get an interrupt signal, allowing provider installation
to abort early while still atomically completing any local-side effects
that may have started.

internal/getproviders: decode and return any registry warnings (#25337)
* internal/getproviders: decode and return any registry warnings

The public registry may include a list of warnings in the "versions"
response for any given provider. This PR adds support for warnings from
the registry and an installer event to return those warnings to the
user.

Kristin Laemmert 8d28d73de3 getproviders: add a registry-specific error and modify output when a
provider is not found.

Previously a user would see the following error even if terraform was
only searching the local filesystem:

"provider registry registry.terraform.io does not have a provider named
...."

This PR adds a registry-specific error type and modifies the MultiSource
installer to check for registry errors. It will return the
registry-specific error message if there is one, but if not the error
message will list all locations searched.

Martin Atkins c8f7223adb internal/getproviders: Source interface for generalization
We intend to support installation both directly from origin registries and
from mirrors in the local filesystem or over the network. This Source
interface will serve as our abstraction over those three options, allowing
calling code to treat them all the same.
