#51 gitlab ci template for runner tag & bytter til public runners

.gitlab-ci.yml

+# Defines a common template for tagging jobs that need runners with the docker
+# exectutor. This was done to be able to change the tag in a single place, as
+# we will likely need to change it every so often. As an example at the time
+# of writing our own runners are slow, so we need to switch back to the public
+# ones
