Add labels and metadata in audit logs of resource against which audits run

[nishant-ui]

The gatekeeper audit pod should have the functionality to emit labels and more details of the resource against which audit ran.
Currently, we get resource name,namespaceetc. It will be good to add labels of the resource as well.

I wonder if we should log the contents of the violating resource, or add the option to do so.

There may be cases where users wouldn't want certain things logged, like the contents of secrets, so we should be careful how we go about this.

Adding the option to include labels sounds interesting. Adding contents of the resource sounds too broad and can create privacy and security issues. Definitely interested to see how many people want this feature. Please +1 if you want this and please indicate what additional data you need.

Adding just the labels should be good enough !

@nishant-ui I reckon davis's #2354 addressed the issue here, right? If so, can we close this issue @maxsmythe ?
