Update HTTP password from SSH commands.

Non-interactive users created from the ssh command line normally can
not logon using the Gerrit web UI. So to create/update a HTTP
password, for REST API usage, one needs to manually update the correct
database table. This change adds support for creating and updating
HTTP passwords from the command line.
