increase webhook timeout values to be larger than probe timeouts.

[n3wscott]

Fixes ##5172

Proposed Changes

• Increase Webhook timeout config from 2 seconds to 10 seconds. At minimum this value should have been larger than the default probe timeout (3 x 1 second). 2 seconds timeout means the LB would fail to route requests if a terminated and not removed pod out of the LB for the webhook.

Release Note

Webhook timeout for API server calls has been increased to 10 seconds.
