VOL-1845 : Support for delete device in openolt adapter
This commit is for the handling of delete device.
The changes are done to handle the request for delete
device. This includes the clearing of all data related
to the device in KV store and reboot of device to reset
the device.
This commit has dependency in voltha-go so that needs to
be merged first. Please refer this review link
https://gerrit.opencord.org/#/c/15084/
Updated to dep ensure above voltha-go patch set. Also typo
and make lint/sca fixes.
