The github status requirements matching and trigger filter are
currently plain text matching based. This currently limits sharing of
pipeline definitions between tenants as zuul reports the status as
'<tenant>/<pipeline>'. This currently makes it necessary to define
trigger filter for each tenant [1] and completely blocks pipeline
requirements.
A solution to this is regex matching which makes it possible to define
the filter once [2].
Further this enables an interesting further use case to trigger on any
successfull status [3]. This makes it easier to cooperate with other
CI systems or github apps which also set a status.
Directly use re2 as this will be used in the future for regex
matching.
