Unable to recreate integration with the same name on OCP 3.11

There are different outcomes for following scenario:

1. create integration with name 'abc'
2. wait until the integration is running
3. delete the integration 'abc'
4. create a new integration with name 'abc'

on OCP 3.11:

• new build is not performed as the build is stuck creating a build object here: https://github.com/syndesisio/syndesis/blob/master/app/server/openshift/src/main/java/io/syndesis/server/openshift/OpenShiftServiceImpl.java#L91
• also no new integrations are being built as the server is stuck there ^, only the server restart helps

minishift with 3.11:

• https://issues.redhat.com/browse/ENTESB-12329

OCP 4.2 :

• same as on minishift

The problem is that the openshift build object is not deleted when deleting buildconfig for the integration here: https://github.com/syndesisio/syndesis/blob/master/app/server/openshift/src/main/java/io/syndesis/server/openshift/OpenShiftServiceImpl.java#L495

The culprit is most likely the bump of the openshift client version here: https://github.com/syndesisio/syndesis/pull/7062
