Add the NSH SFC functional test cases.

	1. Proxy Inbound test with 152/256/512/1024/1280/1518 Bytes VxLAN-GPE + NSH packet
	2. Proxy Outbound test with 128/256/512/1024/1280/1518 Bytes VxLAN packet
	3. SFC SFF test with 152/256/512/1024/1280/1518 Bytes VxLAN-GPE + NSH packet

	Separate the functional test bootstrap file to another code review.
