[release/13.0] Allow HostUrl to remap both address and port

[github-actions]

Backport of #12521 to release/13.0

/cc @danegsta

Customer Impact

3 big ones:

• When using WithOtlpExporter we inject a HostUrl object that gets rewritten depending on if it's a container or not. With @karolz-ms tunneling changes we missed a case where both the host and port need to be rewritten. This makes that work (before we used to assume host.docker.internal so that wasn't necessary)
• We made a big API change introducing ValueProviderContext to IValueProvider.GetValueAsync. This properly flows the context everywhere and changes the ValueProviderContext API (which is not currently experimental)

Testing

Manual and unit tests updates.

Marking this as approved as it is part of the experience for new container tunneling. @davidfowl and @danegsta, given it is marked as medium risk, any particular scenarios we should bash on to have a higher confidence on this?

[davidfowl]

@joperezr we need to merge this ASAP. @danegsta Can you fix the merge here and approve. We can do additional testing.
