Support the functions of state transition in M2 Python controller (ts_m2com). This will issue the power/CLC/ILC related commands directly to the cell controller (ts_mtm2_cell). The target is to get ride of two state machines exist in the M2 server LabVIEW project (ts_mtm2). The M2 Python GUI (ts_m2gui) can use these new functions directly. For the M2 Python CSC (ts_m2), it may need to wait until I finished the update of M2 cell LabVIEW project (ts_mtm2_cell).
