Subject: 	Change the bootstrap script file and test the CI-management.
X-Git-Url: https://gerrit.fd.io/r/gitweb?p=csit.git;a=commitdiff_plain;h=050ece3a87fbbad7d04e69ed951c48118edf0a89

	Change the bootstrap script file and test the CI-management.
	Debug the NSH SFC functional test.
	Change the test cases and not use the tcpdump.
	Delete the unused code.
	Change the directory structure.
