Review request for mesos, Benjamin Hindman, Ben Mahler, and Vinod Kone.


Addressed Ben Mahler's latest review.

Bugs: MESOS-749

Repository: mesos-git


Running tasks on more than one offer belonging to a single slave can be useful in situations
with multiple out-standing offers.

This patch extends the usual launchTasks() to accept a vector of OfferIDs. The previous launchTasks
(accepting a single OfferID) has been kept for backward compatibility, but this now calls
the new launchTasks() with a one-element list.
This also applied for the JNI and python interfaces, which accepts both formats as well.

Offers are verified to belong to the same slave and framework, before resources are merged
and used.

Three new tests has been added: LaunchCombinedOfferTest, LaunchAcrossSlavesTest and LaunchDuplicateOfferTest
This test ensures that:
1) Multiple offers can be used to run a single task (requesting the sum of offer resources).
2) Offers cannot span multiple slaves.
3) No offers can appear more than once in offer list.

$ make check
[ RUN      ] MasterTest.LaunchCombinedOfferTest
[       OK ] MasterTest.LaunchCombinedOfferTest (2010 ms)
[ RUN      ] MasterTest.LaunchAcrossSlavesTest
[       OK ] MasterTest.LaunchAcrossSlavesTest (3 ms)
[ RUN      ] MasterTest.LaunchDuplicateOfferTest
[       OK ] MasterTest.LaunchDuplicateOfferTest (3 ms)
