Subject: [PATCH] Add a handler to the WebRTC operator for context.

We may be running in environments where only the WebRTC operator is
exposed. This can make it difficult to verify information about that
environment; for example, is the operator (and cvd, etc.) running
in a container, or not? One simple way to do this is to expose an
endpoint on the operator for debugging purposes, and one simple way
to get information about the environment is to expose the hostname.

For now, we just expose the hostname, but it may be worthwhile adding
extra fields in the future.
