bonding: T3543: add support to configure lact-rate (slow or fast)

Option specifying the rate in which we'll ask our link partner to transmit
LACPDU packets in 802.3ad mode.

  set interfaces bonding bond0 lacp-rate <slow|fast>

slow: Request partner to transmit LACPDUs every 30 seconds (default)
fast: Request partner to transmit LACPDUs every 1 second
