  1. Add teamd patches to solve traffic loss issue when removing port from…

    … LAG (sonic-net#14002)
    
    #### Why I did it
    When removing port from LAG while traffic is running thorough LAG there is traffic disruption of 60 seconds.
    Fix issue sonic-net#14381
    
    #### How I did it
    The patch I added introduces "port_removing" op and call it right before Kernel is asked to remove the port. 
    Implement the op in LACP runner to disable the port which leads to proper LACPDU send.
    
    #### How to verify it
    Set LAG between 2 switches.
    Set LAGs to be router port and set ip address.
    In switch A send ping to ip address of LAG in switch B.
    In switch B, while ping is running remove port from LAG.
    Verify ping is not stopping.
