Consistent Names for ControllerRevisions, ReplicaSets, and objects using GenerateName

**What this PR does / why we need it**:
Adds the rand.SafeEncodeString function and uses this function to generate names for ReplicaSets and ControllerRevisions.

```release-note
The names generated for ControllerRevision and ReplicaSet are consistent with the GenerateName functionality of the API Server and will not contain "bad words".
