snat health check generate too many api server updates

[Rudra Rugge]

SNAT and LBAAS are launched in a network namespace on a chosen vrouter. The vrouter selection happens based on the
UVE information from analytics. When service monitor detects that the vrouter is down then it tries to reschedule the
snat/lbaas netns to another vrouter.

This requires the virtual-machine placeholder object to be detached from the existing failed vrouter to a new vrouter. The
bug in the code misses the detach operation as information is not sent correctly to the api server. This causes a bunch of
messages/updates to the API server on a regular interval. The fix now correctly updates the virtual-machine and vrouter
references so that a new vrouter can be attached to the virtual-machine.

Snat health check generates unnecessary api server updates

On vrouter down detach infro is not sent correctly to the api server. This causes a bunch of
messages/updates to the API server on a regular interval. The fix now correctly updates the
virtual-machine and vrouter references so that a new vrouter can be attached to the vm.

In addition made the service check interval configurable in contrail-svc-monitor.conf
check_service_interval=<seconds>
