DREIMP-10890: Implement restart for vitess components

[siadat]

Problem

We'd like to be able to restart vtgate or other components of a Vitess instance without restarting all components for that instance.

Solution

Update annotations to trigger a restart for the deployments or recreate the pods. Allow user to specify Vitess deployment they want to restart using dot notation.

vtgate

Commands:

$ paasta restart -s vitess-k8s -c kind-sina-k8s-test -i vitess-tablet-sets.vtgate
$ paasta restart -s vitess-k8s -c kind-sina-k8s-test -i vitess-tablet-sets.vtgate.uswest1adevc

Updated annotations

$ KUBECONFIG=./k8s_itests/kubeconfig kubectl -n paasta-vitessclusters get vitesscluster -o json | gron | grep desired_state | grep 'gateway.annotations'
json.items[0].spec.cells[0].gateway.annotations["paasta.yelp.com/desired_state"] = "start";
json.items[0].spec.cells[0].gateway.annotations["paasta.yelp.com/desired_state_updated_at"] = "2024-09-18T20:09:46.298574+00:00";
json.items[0].spec.cells[0].gateway.annotations["yelp.com/desired_state"] = "start";
json.items[0].spec.cells[1].gateway.annotations["paasta.yelp.com/desired_state"] = "start";
json.items[0].spec.cells[1].gateway.annotations["paasta.yelp.com/desired_state_updated_at"] = "2024-09-18T20:09:46.298574+00:00";
json.items[0].spec.cells[1].gateway.annotations["yelp.com/desired_state"] = "start";
