Justin Santa Barbara ffb6cd61aa Rolling-update validation harmonization 
This is a follow-on to #8868; I believe the intent of that was to
expose the option to do more (or fewer) retries.

We previously had a single retry to prevent flapping; this basically
unifies the previous behaviour with the idea of making it
configurable.

* validate-count=0 effectively turns off validation.

* validate-count=1 will do a single validation, without flapping
  detection.

* validate-count>=2 will require N succesful validations in a row,
waiting ValidateSuccessDuration in between.

A nice side-effect of this is that the tests now explicitly specify
ValidateCount=1 instead of setting ValidateSuccessDuration=0, which
had the side effect of doing the equivalent to ValidateCount=1.

Justin Santa Barbara 31bb16d4d1 Add context.Context to most signatures 
The client-go signature for most methods adds a context.Context
object, and also makes Options mandatory.  Feed through a
context.Context through many of our methods (but use context.TODO to
stop it getting totally out of hand!)

Peter Rifel 237a125f2c Add labels to OWNERS files 
This will automatically label PRs that touch these directories.

This makes it easier to query GitHub for PRs that affect certain areas of the code.

I mostly used existing labels but created some new ones as well.

Justin Santa Barbara 8373c9fc4d tests: increase timeout in rolling update tests 
We never know when e.g. a GC is going to delay us, so we need a lot
more padding on these timeouts.
