Adding loadbalancer service

This commit creates a secret which defines a haproxy.cfg and mounts
that secret to a newly created loadbalancer pod running with haproxy
image. A nodeport service is then created for the loadbalancer pod. The
loadbalancer is created to load balance the nodes defined as master.

-The SIP Cluster operator will manufacture a jump host pod specifically for this

-create a configmap to bind mount into the pod so it understands what host IPs
-represent the clusters.
-
-The expectation is the Jump Pod runs `sshd` protected by `uam` to allow
-operators to SSH directly to the Jump Pod and authenticate via UAM to
-immediately access their cluster.
-
-It will provide the following functionality over SSH:
-
-- The Jump Pod will be fronted by a `NodePort` service to allow incoming ssh.
-- The Jump Pod will be UAM secured (for SSH)
-- Bind mount in cluster-specific SSH key for cluster
-- Ability to Power Cycle the cluster VMs
-- A kubectl binary and kubeconfig (cluster-admin) for the cluster
-- SSH access to the cluster node VMs
-- Libvirt console logs for the VMs
-  - We will secure libvirt with tls and provide keys to every jump host
-    with curated interfaces to extract logs remotely for all VMs for their
-    clusters.
