dhclient: T6667: Added workaround for communication with FRR
To increase the chance for dhclient to configure routes in FRR, added a workaround. Now 10 attempts are performed with 1 second delay and only after this dhclient gives up. (cherry picked from commit da64a7246e9b12d5bd84287517cfbfa59e364c28)
