* Allow deploying the Keycloak and Postgres servers to Minishift and Openshift Online.
This is related to https://github.com/redhat-developer/rh-che/issues/303
and https://github.com/redhat-developer/rh-che/issues/302
* Make the Che directory readble for any users
* Modify `deploy_che.sh` to support `multi-user` images
* Move the scripts to `che-init` and enhance `deploy-che.sh` to start the secondary server if necessary and wait for postgres to be available.
* Wait for Postgres to be available before starting Keycloak
* Clean scripts through spellcheck and add missing licenses
* Change the health check to `/api` instead of `/api/system/state` since, with the new permission work, accessing `/api/system/*` requires the user to have specific system rights.
* Fixes after comments on PR
* Use the new official `keycloak-openshift` image and manage web-origins
* Make Keycloak memory limits consistent with official requirements defined
