[pycue] Make monitoring imports unconditional

Remove conditional try/except around monitoring proto imports and MONITORING_AVAILABLE flag. Monitoring functions should always be available in pycue - if monitoring is disabled at cuebot level, it will return grpc.Status=UNIMPLEMENTED rather than failing at import.

This allows toggling monitoring at the Cuebot end without requiring a new version of pycue.
