Programmatically create a container with Drush

Two patches are attached, one for 2.0.x and one for 8.x-1.x.

The approach here is to provide an MVP, where the drush command simply uses the settings defaults and adds a GTM ID.

Subsequent work could be done to provide more parameters in the drush command.

For 2.x at least, all validation is skipped, so this patch should at least ensure the same validation we use in the form applies to the command.

Good call. The attached patch adds validation using the existing pattern from TagContainer::GOOGLE_TAG_MATCH in the Drush command.

I was able to successfully create containers with drush. Validation checks out as well. Moving to RTBC.
