Subject: [docker] Use image IDs instead of tags
X-Git-Tag: danube.1.0~228^2
X-Git-Url: https://gerrit.opnfv.org/gerrit/gitweb?a=commitdiff_plain;h=7d74359c647fd8950d3f7f28fcc6e49c5587e0f6;p=releng.git

[docker] Use image IDs instead of tags

If we use tags, when there are remaining images without
the tag <none> it fails and get the following error:

Removing docker image opnfv/functest:<none>...
Error response from daemon: Error parsing reference:
"opnfv/functest:<none>" is not a valid repository/tag

By using IDs we make sure we delete the images.
