Weimin Yu df4e345961 Remove appengine-based email client (#2354) ...

Remove email classes that depend on AppEngine API. They have been
replaced by the gmail-based client.

Remove `EmailMessage.from` method, which is no longer used.
There is a fixed sender address for the entire domain, and is
set by the gmail client.

The configs remain to be cleaned up. There is a bug (b/279671974) that
tracks it.
