Merge pull request #49850 from m1093782566/service-session-timeout

Automatic merge from submit-queue (batch tested with PRs 49850, 47782, 50595, 50730, 51341) Paramaterize `stickyMaxAgeMinutes` for service in API **What this PR does / why we need it**: Currently I find `stickyMaxAgeMinutes` for a session affinity type service is hard code to 180min. There is a TODO comment, see https://github.com/kubernetes/kubernetes/blob/master/pkg/proxy/iptables/proxier.go#L205 I think the seesion sticky max time varies from service to service and users may not aware of it since it's hard coded in all proxier.go - iptables, userspace and winuserspace. Once we parameterize it in API, users can set/get the values for their different services. Perhaps, we can introduce a new field `api.ClientIPAffinityConfig` in `api.ServiceSpec`. There is an initial discussion about it in sig-network group. See, https://groups.google.com/forum/#!topic/kubernetes-sig-network/i-LkeHrjs80 **Which issue this PR fixes**: fixes #49831 **Special notes for your reviewer**: **Release note**: ```release-note Paramaterize session affinity timeout seconds in service API for Client IP based session affinity. ```
