Features/ams new interface

[koparasy]

This PR adds the new interface, and allows AMS to read in "Tensors".

Pending Tasks:

• update examples
• support rmq for tensors
• update CI to reflect the changes
  • Update gitlab CI
  • Update github CI
  • Enable RMQ CI
• Convert examples as external packages. Allowing to link in properly AMS
• Add tests in which we link as an external project (not the way we do now).
• Edit the main cmake file
• Generate models at configure time, instead of build time.
• Distributed executions should be put back in cause of update-model.
• Update ams_bench_db.cpp to new testing infrastructure.
• Remove AMS_CSV from db_types.

After discussion with @rblake-llnl we need the following as well:

• some convention in dynamically detecting the type/device of the loaded model. I can think of the following approaches:

1. Add an attribute in the model itself that specifies this, and just set the attribute before freezing (use preserve_attrs) flag on torch freeze to keep this in the jitted model.
2. Add a JSON option to read that in from the environment.

• print messages regarding the selected device and model

@lpottier I assigned you as a reviewer. This is a complete refactor. I redid many points. In any case reviewing the changes will be hard, I understand. Would you like maybe to setup some meeting and do a code walk through? Let me know.

I should always find package in the AMSConfig.cmake.in
