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.
