bfd: T1183: add support to configure detection multiplier
Configures the detection multiplier to determine packet loss. The remote transmission interval will be multiplied by this value to determine the connection loss detection timer. The default value is 3. Example: when the local system has detect-multiplier 3 and the remote system has transmission interval 300, the local system will detect failures only after 900 milliseconds without receiving packets.
