Adding pairing request with authentication as "RequestPinCode"

Adding outgoing pairing request with another BT device when we call pair verb.
"RequestPinCode" is handled as xml into bluetooth-agent.c to confirm a pincode and send it to BT device when we call pair request from AGL device to other device.

Bug-AGL: SPEC-3610
