Allow overriding environment variable with gitlab-runner exec
I have variables defined inside of my
.gitlab-ci.yml which I would like to override when running
gitlab-runner exec. Using
gitlab-runner exec --env does not work as described in #3996 (comment 144993024)
Create a new flag
--override-env that will allow me to override any environment variable that is defined from the config file or from the
.gitlab-ci.yml for local development purposes.
