  1. tetragon: Add load mutex for sensor manager 

    We already lock access to the collections and we depend on the
queue serialize policy/sensor loads/unloads.

Following change will remove the queue, but we still want to keep
the loads/unloads serialized, so adding lock for that.

  5. tetragon: Load initial sensor via sensor manager 

    Loading initial sensor via sensor manager so it stores all the
loaded sensors/programs. So far we kept it separated but having
it in one place is handy for metrics requesting this data.

Moving the load before the server is started so we don't need to
"wait" for that. This way we can remove the sensorMgWait channel.
