Added a new ReventWorkload as a base for revent based workloads.
Updated ReventGui to use `revent_recorder` and now uses `target.model`
instead of `taget.name`.
Added a workload type to handle workloads that have both an APK with an
application and associated automation JAR. Added benchmarkpi
implementation using using the new workload.
- Implemented result processor infrastructured
- Corrected some status tracking issues (differed between states
and output).
- Added "csv" and "status" result processors (these will be the default
enabled).
- Fixed up some of the signal map for instrumentation
- Changed how priorites are specified -- no longer method name prefixes
but dedicated decorators, including an easy way of specifying a custom
priority level (no longer need to manually connect signals)
- Updated ExecutionTimeInstrument to work with the new system
- Also removed some dead code
Changing the way target descriptions work from a static mapping to
something that is dynamically generated and is extensible via plugins.
Also moving core target implementation stuff under "framework".
