Ftrack: Show OpenPype versions in event server status

[iLLiCiTiT]

Description

Show OpenPype versions in event server status action for both zip and build. Also show executable path (or path to start.py when running from code).

Changes

• renamed get_pype_version to get_openpype_version (get_pype_version kept for backwards compatibility of opened PRs)
• added is_running_from_build function to be able know it openpype is running from code or build
• added get_build_version which should return version of build even if is not currently running version
• use new functions to pass information about processes to statuser
• information about processes are passed as list of lists to keep order
  • statuser was modified to be able handle that situations (require restart of whole event server)

How to test

• run ftrack event server
• run OpenPype Admin - Event server Status (...) action
• all processes should have information about openpype version they're using and main process should have information about executable path (start.py path when running from code)
