Fix some flakes in autoscaler e2e on gke
This PR should fix some of the flakes we found in e2e runs, while testing for 1.7 release:
- if one of the nodes is unschedulable in set up (causing set up to fail) we used to wait for wrong number of nodes in clean-up, adding unnecessary 20 minute wait to failing test
- we did not check for errors when creating RC in test, leading to tests failing later in hard to debug way (added retry loop and explicit test failure)

Further reduce cluster-autoscaler e2e flakiness
Ref: https://github.com/kubernetes/autoscaler/issues/89
Add pdbs for additional kube-system pod, move adding
pdbs to separate function, as it will need to be reused
in new tests we're working on (ex. scale to 0).
