Tao Liu 5c8377047b Move subcloud audit to separate process
Remove subcloud audit from dcmanager-manager process.
Create dcmanager-audit process & associated files.
Add new RPC calls for dcmanager-audit to notify dcmanager
subcloud availability and sync endpoint type changes.
Update dcmanager to handle availability and sync endpoint
type updates from dcmanager-audit.
Subcloud audit interval will be reduced to 20 seconds.
Create/update unit tests, to verify the implementation
changes.

$0 manages an OpenStack DC Manager Audit service (dcmanager-audit) process as an HA resource
The 'start' operation starts the dcmanager-audit service.
The 'stop' operation stops the dcmanager-audit service.
The 'validate-all' operation reports whether the parameters are valid
The 'meta-data' operation reports this RA's meta-data information
The 'status' operation reports whether the dcmanager-audit service is running
The 'monitor' operation reports whether the dcmanager-audit service seems to be working
