Investigate jenkins test failure on OCP 4.10 for interop

Jenkins test suite failing on interop program for 4.10

Interop Issues
https://issues.redhat.com/browse/LPINTEROP-2307
https://issues.redhat.com/browse/LPINTEROP-2416

Root Cause
we have a bug open for which our test are failing.
Add xmlstarlet to handle JENKINS_PASSWORD

Per discussion in team scrum, this is not a release blocker. The JENKINS_PASSWORD path is not the default way we deploy Jenkins - default is using the oauth plugin.

Action Plan
We have fixed this issue in 4.11 and are expecting a back port to 4.10 . But the team has decided releasing this in an early z-stream.

But for time being we are not going to run the test related to this which is causing failure on interop.
