Closes #1

See merge request !1

Add Synapse and reverse proxy companion to the required services list; We need these in order to get our admin access token on startup.

Put _matrix_ in the variable names for our Matrix username/password so it's clear what these are for

Use the MDAD playbook's variable for the homeserver URL instead of hardcoding the master Synapse process.  This lets us use Synapse workers, or potentially a different homeserver.
