Docker: allowed_images (question)

Hi.

First of all, thank you for great tool.

I have a question about allowed_images. I have two runners. One for PHP7 and one for old PHP56. Each runner has a section with allowed docker image. Lets say allowed_images = ["dockette/ci-php7:*"].

Sometimes happened that wrong runner has been picked up for a build. There is of course a known message The dockette/ci-php7 is not present on list of allowed images.

I have been thinking if there is a allowed_images configuration present, gitlab-ci-multi-runner will pick up right runner.

Thank you guys for you help.
