Benjamin Welton 4a5b1d98c2 SDK: counter collection serialization per device (#1157)
Migrates profiler_serializer class in QueueController to have an instance per-agent instead of one globally. Other changes in this commit are to allow for maps of the queues associated with each agent to be passed to profiler_serializer when it is turned on/off. Existing test cases cover whether or not the kernels are serialized (multistream app). New test case added to show that this serialization only occurs on a per device level with a kernel launched on one device waiting for a value to be set on the other.
