Add zebra -K --graceful_restart argument

https://docs.frrouting.org/en/latest/zebra.html#cmdoption-zebra-K With that argument `-K 120`, when zebra stops it does not clean the routes that has install on the host. When zebra starts up with, it will wait 120 seconds before removing (sweeping) any routes that it previously created but are no longer valid. This is needed to complete the BGP graceful restart feature when the local endpoints depend on local routes that are learned from the BGP peer. Downside is that if we simply remove FRR (delete deployment or change speaker label toleration) those routes will remain on the host until reboot. Signed-off-by: karampok <[email protected]>
