Review request for mesos, Benjamin Hindman, Ben Mahler, and Vinod Kone.
Changes
-------
Attached JIRA issue.
Bugs: MESOS-749
https://issues.apache.org/jira/browse/MESOS-749
Repository: mesos-git
Description
-------
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.

Testing
-------
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.
