openstack_release 'auto' makes invalid tagging for image

[Yang Youseok]

I'm afraid that it was users fault who does not know the variable's meaning though,
when I use 'openstack_release = auto' which is default docker was trying to find image with tagging which is same as 'kolla ansible itself'.

It means if I use kolla-ansible which have 8.1.0 tagging, any docker images could not found since kolla docker image does not have 8.1.0 tag.

Pbr versionInfo use pip version rather than git branch tagging, currently it never found valid image.

Thanks

This is by design, although I agree it is not very intuitive. We should use the release name as the default tag, since this is what we publish to Dockerhub.

@Mark Hi, any idea to get the branch name just like using "pbr" to get tag? should we store the git branch name to the file?

[Mark Goddard (mgoddard)]

@Chason, I suggest we just keep it static for now, and put it on the list of things we need to change when we cut a release branch. So in master we just set openstack_release to master.

OK, I will commit a patch soon, thanks! :)

    Update "openstack_release" variable to static brach name

    Since we use the release name as the default tag to publish images
    to Dockerhub, we should use this by default.

    This change also removes support for the magic value "auto".
