add deploy.sh for simpler deployment

This makes it simpler for users to deploy the operator. Users
won't need a checkout of the github repo, instead they can just
run a shell script which takes care of creating all ressources,
deploying the operator and creating a custom ressource.

Changed README.md to reflect these changes.

+  ``` curl https://raw.githubusercontent.com/openshift/kata-operator/master/deploy/deploy.sh | bash ```
