Add script to initialized openbmc env in Kubernetes

Added a new script that can be used to deploy all neccessary objects
required to do builds into the Kubernetes API. It also has the added
function of being able to deploy a Jenkins master into Kubernetes using
the "build-jenkins.sh" script.

Updated the storage-setup.sh to use lowercase variable names.

+###############################################################################
+#
+# This script is for initializing the Kubernetes environement needed to run all
+# the kubernetes integrated scripts in Kubernetes.
+# - Provisions the PV's and PVC's for:
+#   * The Kubernetes JNLP Jenkins slave's shared workspace
+#   * Shared state cache
+#   * Openbmc/openbmc git reference repository
+#   * Openbmc/qemu git reference repository
+# - Create docker-registry secret for pulling from the internal repo
+# - Create the config.json used to mount docker configuration to Kubernetes
+#   Jenkins slaves that build and push docker images via shell scripts.
+# Optionally:
+# - Launch a Jenkins Master deployment into Kubernetes.
+# - Provision the PV and PVC for the Jenkin Master home directory
+#
+# Instructions:
+#  Suggested way to run is to create a seperate script that will export all the
+#  necessary variables and then source in this script. But editing this one
+#  works as well.

+# Requirements:
+#  - NFS server with directory to use as path for mount
+#  - Access to an existing Kubernetes Cluster
+#  - Kubectl installed and configured on machine running script

+# Variables used to initialize environment:
+#  ns           = Name of namespace we will be deploying the components into,
+#                 defaults to "openbmc".
+#  nfsip        = IP address of the NFS server we will be using for mounting a
+#                 Persistent Volume (PV) to, defaults to "10.0.0.0", should be
+#                 replaced with an actual IP address of an NFS server.
+#  reclaim      = The reclaim policy that will be used when creating the PV
+#                 look at k8s docs for more info on this. Defaults to "Retain".
+#  path_prefix  = The prefix we will add to the nfspath of the directories we
+#                 intend to mount. This is used to place all the different
+#                 directories into the same parent folder on the NFS server.
+#                 defaults to "/san_mount/openbmc_k8s", should be changed to
+#                 a valid path on your NFS server.
+#  regserver    = The docker registry which will be used when pushing and
+#                 pulling images. For internal use, it will be the internal
+#                 registry created by ICP, defaults to "master.icp:8500" must
+#                 be changed to an actual registry.
+#  username     = The username that will be used to login to the regserver,
+#                 defaults to "admin", should be changed.
+#  pass         = The password that will be used to login to the regserver,
+#                 defaults to "password", should be changed.
+#  email        = The email that will be used to login to the regserver,
+#                 defaults to "email@place.holder", should be changed.
+#  k8s_master   = Set to True if you want to deploy a Jenkins Master into k8s,
+#                 defaults to True.
