Code Issues Proposed changes

Disable old DSE code 

- Move tests2 to tests
- Disabled a few tests that require porting to new DSE
  and marked with TODO(dse2)
- Removed all the distributed_architecture checks
- Fixed api_driver_model and upgraded tests to dist_arch

Still need to remove dse code and deal with fallout
Still need to remove dead code from some api models
But this patchset is large enough, so save rest for
future work.
