Add support for Guru Meditation Reports for LBaaS agents

The change consolidates common actions taken by all services under
neutron_lbaas/cmd/... in a way that reflects the approach taken in
neutron repo. This currently includes GMR initialization and eventlet
monkey patching.

Added oslo.reports dependency since now we explicitly require it.
