Support negative matches in .gitlab-ci.yml
What does this issue do?
This adds support in only/except:variables:
support for !=
and !~
operators.
This is the most naive approach. For example:
($AA == "AAA") && ($BB == "CCC") && ($DD == "XXX")
except:
variables:
- $AA != "AAA"
- $BB != "CCC"
- $DD != "XXX"
