Multiple changes to deploy scripts

[ghost]

What does this PR do?

1. Makes deploy_che.sh autonomous, ie the script can download templates without the need for a user to clone the entire repo. Once merged this script will be the default way to deploy Che to OpenShift in official documentation.
2. Improves wait functions in deploy_che.sh. Using jq and parsing statuses isn't the right way to go. Instead, waiting for deployment replica is a foolproof way. It uses less code, and this approach is used in Ansible playbooks when waiting for a deployment
3. Get rid of jq in deploy_che.sh since wait functions use -o=jsonpath rather than jq now, which is a true oc way.
4. Get rid of jq in ocp.sh - the only function it was used in was the function that waited for ocp full boot. We do not use an internal docker registry in Origin at all during Che deployment. I'd say it's a legacy function since we indeed used s2i for Che multiuser (not anymore)
5. Check if oc binary of the right version is present in PATH - downloading archives from GitHub takes time

Looks like the formatting is a bit broken. Please consider reformatting:

getTemplates(){
  if [ ! -d "${BASE_DIR}/templates" ]; then
    printInfo "Local templates directory not found. Downloading templates..."
    curl -s https://codeload.github.com/eclipse/che/tar.gz/master | tar -xz --strip=3 che-master/deploy/openshift/templates -C ${BASE_DIR}
    OUT=$?
    if [ ${OUT} -eq 1 ]; then
      printError "Failed to curl and untar Eclipse Che repo because of an error"
      printInfo "You may need to manually clone or download content of https://github.com/eclipse/che/tree/master/deploy/openshift and re-run the script"
      exit ${OUT}
    else
      printInfo "Templates have been successfully saved to ${BASE_DIR}/templates"
    fi
  else
    printInfo "Templates directory found at ${BASE_DIR}/templates. Applying templates from this directory. Delete it to get the latest templates if necessary"
  fi
}

Consider using tools for formatting.
The following is right here:

    if [[ $(oc version 2> /dev/null | grep "oc v" | cut -d " " -f2 | cut -d '+' -f1 || true) == *"$OC_VERSION"* ]]; then
        echo "Found oc ${OC_VERSION} in PATH. Using it"
        export OC_BINARY="oc"
    elif [[ ! -f $OC_BINARY ]]; then
        download_oc
    else
        # here we check is installed version is same version defined in script, if not we update version to one that defined in script.
        if [[ $($OC_BINARY version 2> /dev/null | grep "oc v" | cut -d " " -f2 | cut -d '+' -f1 || true) != *"$OC_VERSION"* ]]; then
            rm -f "$OC_BINARY" "$OCP_TOOLS_DIR"/README.md "$OCP_TOOLS_DIR"/LICENSE
            download_oc
        fi
    fi

It might be better to check for non zero return code as there are other error code other than 1
