PLDM: implement surveillance between Host and bmc

This commit is to implement surveillance between host
and bmc, wherein host monitors if bmc is up and
running through constant pings(by sending Platform
EventMessages) sent from host to BMC. And if BMC
fails to respond to the pings, then BMC will be
reset using the KCS interface.

1. Host->BMC - GetTID
2. BMC->Host - Respond to GetTID, SetEventReceiver
3. Host->BMC - Respond to SetEventReceiver
4. BMC->Host -  Send PlatformEventMessage after the
   elapsed time interval(specified with
   SetEventReceiver command)
4. Host->BMC - If BMC fails to send respond to host
   within specified interval, Host resets BMC via
   the KCS interface

Tested with PLDMTOOL:
SetEventReceiver command:
root@rain127bmc:/tmp# ./pldmtool base GetTID -m 8
Received Msg
08 01 81 00 02
Sending Msg
01 00 02 00 01
{
    "Response": 1
}

platformEventMessage command(which will be received
by host):
root@rain118bmc:/tmp# ./pldmtool raw -d 0x80 0x02
0x0A 0x01 0x01 0x06 0x01 0x01
