Container Support

Add the ability to limit tag using a regexp

For example:

upstream taglist is

[
'openshift-4',
'openshift-3.11'
'openshift-3',
'openshift-3.10'
'latest'
'foo'
]`

When specifying whitelist-tags=[openshift-3.*, latest, bla-bla] it will mirror down only:

[
'openshift-3.11'
'openshift-3',
'openshift-3.10'
'latest'
]
