internal/getproviders: LookupLegacyProvider This is a temporary helper so that we can potentially ship the new provider installer without making a breaking change by relying on the old default namespace lookup API on the default registry to find a proper FQN for a legacy provider provider address during installation. If it's given a non-legacy provider address then it just returns the given address verbatim, so any codepath using it will also correctly handle explicit full provider addresses. This also means it will automatically self-disable once we stop using addrs.NewLegacyProvider in the config loader, because there will therefore no longer be any legacy provider addresses in the config to resolve. (They'll be "default" provider addresses instead, assumed to be under registry.terraform.io/hashicorp/* ) It's not decided yet whether we will actually introduce the new provider in a minor release, but even if we don't this API function will likely be useful for a hypothetical automatic upgrade tool to introduce explicit full provider addresses into existing modules that currently rely on the equivalent to this lookup in the current provider installer. This is dead code for now, but my intent is that it would either be called as part of new provider installation to produce an address suitable to pass to Source.AvailableVersions, or it would be called from the aforementioned hypothetical upgrade tool. Whatever happens, these functions can be removed no later than one whole major release after the new provider installer is introduced, when everyone's had the opportunity to update their legacy unqualified addresses.
