Sync structure of profile_* code for optimization

[mrakitin]

Need to have all three codes structured consistently:

• flyer classes are in separate modules
  • profile_collection
  • profile_sirepo
  • profile_simulated_hardware
• optimization functions are in a separate package, and are imported in the profile_*
  • profile_collection
  • profile_sirepo
  • profile_simulated_hardware
• detector operations and watch functions are in separate modules
  • profile_collection
  • profile_sirepo
  • profile_simulated_hardware
