add more livenessProbe configurability in helm chart for frr container

[PeterGrace]

This PR implements the additional fields available to a livenessProbe for the frr container. The rationale is that I run k8s nodes on SOQuartz arm64 boards and they sometimes can take >1 second to respond to livenessProbe queries. Because the fields were previously undefined, timeoutSeconds was defaulting to 1, leading to the frr container falling into CrashLoopBackOff.

Hi @fedepaol , I've squashed the commits which should be reflected in 2a609b6.

I see the CI shows some unit test and static analysis errors, I don't think that this change would impact those but let me know if I need to do some further investigation there. Thanks!

yep, the failure is not related to this change (and it was already addressed).
LGTM, thanks!
