Fix up force live migration completion docs

Browse Source 
This change does a few things:

* Links live_migration_completion_timeout to the config
  option guide.

* Links the force complete API reference to the feature support
  matrix to see which drivers support the operation.

* Fixes the server status mentioned in the troubleshooting for
  the force complete API reference (a live migrating server
  status is MIGRATING, not ACTIVE). The same text is copied to the
  abort live migration API reference troubleshooting for
  consistency (and since using the server status is more natural than
  the task_state).

* Links to the admin guide for troubleshooting live migration
  timeouts.
