Initial commit of controller services config guide

Initial commit of controller services config guide

- Controller services lump cloverctl CLI and clover-controller
together and this config guide provides brief overview
and deploy/delete instructions
- Intended to be one of the first guides a user follows,
as controller is prerequisite for many other Clover services
- Add new, existing config guides to index
including forthcoming jmeter, visibility guides
- Embedded images forthcoming
