Review request for mesos, Adam B, Alexander Rukletsov, Benjamin Hindman, Greg Mann, and Yong Qiao Wang. Bugs: MESOS-4085 https://issues.apache.org/jira/browse/MESOS-4085 Repository: mesos Description ------- Changed the behavior of the master when the `--roles` flag is NOT specified. Previously, this would allow only the `*` role to be used. Now, omitting `--roles` means that any role can be used. This is called "implicit roles". Configuring which principals can perform operations as which roles should be done using ACLs in the authorization system. Note that this changes the behavior of the system when `--roles` is not specified. This is likely acceptable: if the operator didn't specify `--roles` in prior versions of Mesos, they were likely not using roles or authorization at that time. Another minor behavioral change is that the "/roles" endpoint will now only return results for currently "active" roles (those with one or more registered frameworks). The `--roles` flag is now considered deprecated and will be removed in a future version of Mesos.

TODOs: * Update documentation * I noticed a non-deterministic test failure in "MasterAllocatorTest/1.FrameworkExited" on Ubuntu 15.10. It repros reliably but I haven't determined yet whether it is a flakey test or a bug in this patch. * Add tests for allocation behavior for weights + implicit roles * Add tests for quota + implicit roles? Thanks, Neil Conway
