Review request for mesos and Benjamin Mahler.


Extended the comment on RE2 limits

Bugs: MESOS-10173

Repository: mesos


This patch adds protobuf messages for setting offer constraints
that check if agent's (pseudo)attribute matches a specified RE2 regular

Both added contsraint predicates will evaluate to `true` when the
attribute is not TEXT. This way, schedulers will have to apply on their
own whatever filtration they do for non-TEXT attributes which happen
to be selected by the constraint's `Selector`.

Given that in the real world schedulers seem to rarely put constraints
on attributes that are normally Scalar/Ranges, this should not prevent
them from obtaining performance benefits by setting offer constraints.
