Review request for mesos and Benjamin Mahler.


Changes
-------

Renamed into TextEquals/TextNotEquals; extended the comment


Bugs: MESOS-10172
    https://issues.apache.org/jira/browse/MESOS-10172


Repository: mesos


Description
-------

This patch adds protobuf messages for setting offer constraints
on equality/non-equality of agent's (pseudo)attribute to a specified
string.

Both added contsraint predicates will evaluate to `true` when the
attribute is not TEXT. This way, schedulers will still perform all
filtration based on non-TEXT attributes on their own, which helps to
avoid subtle integration bugs caused by discrepancies in Scalar/Ranges
comparison between Mesos and the scheduler.

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