Policy Controller does not support deployment strategy values

[shearn89]

Description

Looking at the charts for the policy-controller webhook, it does not seem possible to pass in values for the deployment strategy. Specifically things like maxSurge?

My actual problem:

I'm unable to drain a node because I've got policy-controller deployed with replicas: 1, and the default deployment strategy won't let it surge to 2 in order to roll, because the maxSurge defaults to 25% rounded down, i.e. 0.

What I'd like to do:

• Configure the deployment strategy same as other templates.
