Integrate the M2 Python EUI (ts_m2gui) with common module (ts_m2com) in phase 1. This is to reuse the controller in common module (which has been used in the M2 CSC, ts_m2). By doing this, the M2 Python EUI should be able to support the simulation mode and verify its functionality.

The main point in this phase 1 is to remove the duplicated code in ts_m2gui and adapt the qasync.
