* Avoid "bulk-comparing" pod resources during sync.
First attempt to fix bogus restarts due to the reported mismatch
of container resources where one of the resources is an empty struct,
while the other has all fields set to nil.
In addition, add an ability to set limits and requests per pod, as well as the operator-level defaults.
* Add version label to the cluster.
According to the STUPS team the daemon that exports logs to scalyr
stops the export if the version label is missing.
* Move label names to constants.
* Run go fmt
* Add infrastructure roles configured globally.
Those are the roles defined in the operator itself. The operator's
configuration refers to the secret containing role names, passwords
and membership information. While they are referred to as roles, in
reality those are users.
In addition, improve the regex to filter out invalid users and
make sure user secret names are compatible with DNS name spec.
Add an example manifest for the infrastructure roles.
introduce Pod events channel;
add parsing of the MaintenanceWindows section;
skip deleting Etcd key on cluster delete;
use external etcd host;
watch for tpr/pods in the namespace of the operator pod only;
