Bump external cluster testsuite to reflect Management framework reorg
Bump zeek-client to reflect Management framework reorg
Reorg of the cluster controller to new "Management framework" layout
This job runs in sequence after the image build one, using its resulting image.
The actual tests live in the external zeek-testing-cluster testsuite, which
the new job clones and runs.
To specify a version of the testsuite to use, testing/external/ has a new
commit-hash.zeek-testing-cluster file that tracks the testsuite's relevant
commit ref
