test: Increase frequency of wait helpers to 1 per sec
test: Increase frequency of wait helpers to 1 per sec

We use a number of WaitXXX helper function to wait for pods to be
deployed, policies to be enforced, service endpoints to be created, etc.
The default frequency at which these functions check the expected output
is 5s. So for namespace deletions and policy enforcements, we often wait
10s, because the output is not as expected after the first 5s check.

This is unnecessary. We can instead check the output every 1s and shave
off a few seconds every time we wait for something to happen (and we do
that a lot!).
