Issue MESOS-1119: Allocator should make an allocation decision per slave instead of per framework/role.
Currently the Allocator::allocate() code loops through roles and frameworks (based on DRF sort) and allocates *all* slaves resources to the first framework. This logic should be a bit inversed. Instead, the slave should go through each slave, allocate it a role/framework and update the DRF shares.
