Bootstrap to test csit-master against VPP release.
- get the version of the latest VPP build - download and install the latest VPP build on nodes - run three times all test suites to check if the VPP build can be used for csit development and current csit master can be pushed to master-verified branch (see patch https://gerrit.fd.io/r/590) Change-Id: I0ad2e9fe1620cc18ccc11dce2d107177cf97ff27 Signed-off-by: Jan Gelety <jgelety@cisco.com>
