[Feature request] Allow negative matches for regex in match_attributes

[maxlemieux]

This request is to provide an equivalent feature to work around the lack of negative lookahead patterns in Golang regex for match_attributes.

Example which doesn't work (container will crash):

match_attributes:
  "!if_interface_name": "^(?!foobarbaz\b)\\S+"

It would be great if there was an operator to negate the match.

Will this work for you @maxlemieux?

        match_attributes:
            if_interface_name: enp1s0
            DOES_NOT_MATCH: true

A long time ago, the DOES_NOT_MATCH special case was added. It will invert any matches for a match_attributes block where it is present.

Great! This should work nicely for the purpose.
