v2.1.0

FEATURES:

• rancher2-vsphere-cluster: Added possibility to create a single node K8s cluster which could be useful for development, testing and learning purposes; this type of cluster uses a new node role called all_in_one

BUG FIXES:

• rancher2-vsphere-cluster: Fixed default variable value for control_plane node pool, which would cause an error when creating the node pool, since the name should be RFC 1123 compliant
