Replace configmap.yml with Helm chart

This is a sub-issue of https://github.com/amazeeio/lagoon/issues/564#issue-350184516, bullet 5:

Create OpenShift objects (Services, Routes/Ingress, ConfigMaps) based on some given data within .lagoon.yml (happens in https://github.com/amazeeio/lagoon/blob/master/images/oc-build-deploy-dind/build-deploy-docker-compose.sh#L174-L304)

This issue specifically concerns the replacement of the Config Map OpenShift Template with a Helm chart.

# Generate a Config Map with project wide env variables
oc process --local --insecure-skip-tls-verify \
  -n ${OPENSHIFT_PROJECT} \
  -f /oc-build-deploy/openshift-templates/configmap.yml \
  -p NAME="lagoon-env" \
  -p SAFE_BRANCH="${SAFE_BRANCH}" \
  -p SAFE_PROJECT="${SAFE_PROJECT}" \
  -p BRANCH="${BRANCH}" \
  -p PROJECT="${PROJECT}" \
  -p ENVIRONMENT_TYPE="${ENVIRONMENT_TYPE}" \
  -p ROUTE="${ROUTE}" \
  -p ROUTES="${ROUTES}" \
  -p MONITORING_URLS="${MONITORING_URLS}" \
  | oc apply --insecure-skip-tls-verify -n ${OPENSHIFT_PROJECT} -f -

if [ "$TYPE" == "pullrequest" ]; then
  oc patch --insecure-skip-tls-verify \
    -n ${OPENSHIFT_PROJECT} \
    configmap lagoon-env \
    -p "{\"data\":{\"LAGOON_PR_HEAD_BRANCH\":\"${PR_HEAD_BRANCH}\", \"LAGOON_PR_BASE_BRANCH\":\"${PR_BASE_BRANCH}\", \"LAGOON_PR_TITLE\":\"${PR_TITLE}\"}}"
