commit 74537354ec1b2af3e0e0584bb5f277660dff3614

Added protobuf messages for offer constraints on a string equality.
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.
