Subject: [PATCH] Add install script for KServe and ModelMesh (#2032)

Add install script for KServe and ModelMesh so the user can
quickly experiment features provided by two repos.

The script will install all prerequisits knative, istio, cert
manager, etcd, and minio, and create namespaces when needed.
The repo branch variables can be changed to install different
versions of KServe and ModelMesh.

+# deployed in "kserve" namespace, ModelMesh controller is in "modelmesh-serving" namespace,
+# and ModelMesh is enabled for the optional user namespaces in the -u argument or the
