    RDK-43628: Remove Qt dependency from BleRcuDaemon

    Reason for change: Remove all things Qt from BleRcuDaemon and pull in
    that component into the controlManager repository.

    Test Procedure: full remote regression

    Risks:              High

    DELIA-64729: Coordinate Bluez discovery with btmgr

    Reason for change:   If btmgr had a bluetooth scan running
     while a BLE remote was trying to pair, BleRcuDaemon made
    calls into btmgr to coordinate this activity and make sure a
    scan was restarted after the BLE pairing operation finished.

    So this fix ports that functionality from the original BleRcuDaemon
    into ctrlm
    Test Procedure:     see ticket
    Risks:              Low
