bmcweb implementation of NMI (soft reset) control code

Tested : Verified following

  1) Redfish validator result is Negative
  2) verified following command triggered NMI on host
     curl -k -H "X-Auth-Token: $bmc_token" -X POST
     https://9.5.180.47/redfish/v1/Systems/system/Actions/ComputerSystem.Reset
     -d '{"ResetType":"Nmi"}'
     Response : OK
  2) Host rebooted and crash dump is collected
