This commit implements rate limitation for the TCAT commands Present PSKd Hash TLV (0x10), Present PSKc Hash TLV (0x11) and Present Install-code Hash TLV (0x12) to prevent password guessing attacks. It also removes the TCAT command Request PSKd Hash TLV (0x14), to prevent offline password guessing attacks with a single Hash value retrieved from the device. Note: The commit does not remove the Request PSKd Hash TLV implementation in the Python commissioner such that the non-existence of the command TLV can still be tested.
