Upgrade to use jcasc test harness

[timja]

JCasc had to create a new dependency that wasn't a tests classifier because maven doesn't allow you to bring dependencies through classifiers.

Upgrading here so that PCT works again,

Tracking:
jenkinsci/bom#164

Note: We'll need a release for PCT please

@jvz what do you think of backporting this to 1.17.x?

On the bom we're currently getting (jenkinsci/bom#172):

Require upper bound dependencies error for org.jenkins-ci:trilead-ssh2:build-217-jenkins-14 paths to dependency are:
+-io.jenkins.tools.bom:sample:6-SNAPSHOT
  +-org.jenkins-ci.main:jenkins-core:2.176.3
    +-org.jenkins-ci:trilead-ssh2:build-217-jenkins-14

      +-org.jenkins-ci.plugins:trilead-api:1.0.5
        +-org.jenkins-ci:trilead-ssh2:build-217-jenkins-16

I think it's either backport, or fix the bom PR for 2.190.x and then only having new jcasc versions in the bom on >= 2.190.x which isn't ideal.

cc @jglick if you have any other ideas.

If you'd like to backport, please file a PR and I can release from a branch.

can you create the origin branch that I can PR to please?

[timja]

One liner:

git checkout ssh-credentials-1.17.3 && git checkout -b 1.17.x && git push -u origin 1.17.x

[jvz]

Branch created!
