[Despire]

Closes #1683

Adds additional settings for the role:
proxyProtocol - the role will use the proxy protocol for any forwarded traffic
stickySessions - the traffic will be forwarded to the same node based on the hash of the source ip.

The lb role will now have the following structure

  loadBalancers:
    roles:
      - name: example-role
        protocol: tcp
        port: 6443
        targetPort: 6443
        targetPools:
          - htz-kube-nodes
        # added
        settings:
          proxyProtocol: off (default will be on)
          stickySession: on. (default will be off)
