phosphor-host-ipmid : yosemitev2: Add host Identification support

Added host Identification support in ipmid. This helps to
identify the particular hosts. The channel indexes for
hosts are getting from ipmb json config and passed from ipmb.

TESTED : Built Facebook YosemiteV2 & Tiogapass images and loaded on
the target hardware. We are able to see hostId's for all the hosts.

Note : This is the follow-up patch for multiple channels
support in ipmbbridge.
