Pass sandesh from opserver to discoverClient
Pass sandesh from opserver to discoverClient

Currently, when the opserver uses the discoverClient,
the logs are not captured. Specifically, in my case,
this caused the following helpful log messages:

__default__ [SYS_INFO]: discClientLog: connection error or failed to publish

to never show up in my contrail-analytics logs.

A sendeesh object must be passed explicitly to the discoveryClient
in order for logging to work with its set_sandesh method.

This patch ensures that the global sendeesh object is passed
from the opserver to the discoveryClient so that its log messages
are captured.
