Have to periodically restart captain pod to refresh Webhook TLS

Issue seems related to #39 but can be fixed by restarting the captain pod:

I will look into it... I have tested it before, but failed to reproduce this error. Captain generated cert are approved by kubernetes cluster use thr CSR resouce.

You can remove all the captain webhooks for now, it does not affect the core function of captain. This should avoid using of the cert
