Convert update_blueprint to use the Gerrit REST API

This calls the Gerrit REST API to retrieve subject and topic for a
change instead of querying the Gerrit database. The ReviewDb was
removed in Gerrit 3.0 [1], so we need to use the REST API instead.

This also uses the Gerrit API to get the change commit message instead
of running git commands directly in the git directory.
