Have time lord take over rank functionality from dyno bot

[Errolyn]

• Should be able to add ranks to a member
• Should be able to add new ranks
• Should be able to keep track of what ranks are joinable by a member
• Should be able delete old ranks which should remove them from both the server and the bots database
• Ranks should be pingable

This needs some more thought around how this should work from the members perspective, and could be broken out into a few tasks. We will probably need a DB added to timelord to make this work, so we should decide when info is needed and useful to.
