Use Jersey 2 API plugin

[basil]

#107 added jackson-jaxrs-json-provider, which exposed the need for the JAX-RS API. That was added in #111, which exposed the need for a JAX-RS implementation. Since a JAX-RS API and implementation are outside the scope of this plugin, I have created a new Jersey 2 API plugin providing the JAX-RS 2.1 API with Jersey 2 as its implementation. This PR adjusts the Jackson 2 API plugin to consume that new plugin as an optional dependency.

thanks basil. FWIW - if you want to enable CD on the jersey 2 plugin but keep the reasonable version numbering for the dependencies - this plugin is a good example of that.

@jtnord Can you please trigger a release to provide relief to users affected by JENKINS-67506? This was not done automatically, because you specified a label of chore, which is not considered an "interesting category" by the CD process.

@jtnord The release failed with

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy (default-deploy) on project jackson2-api: Failed to deploy artifacts: Could not transfer artifact org.jenkins-ci.plugins:jackson2-api:hpi:2.13.1-246.va8a9f3eaf46a from/to maven.jenkins-ci.org (https://repo.jenkins-ci.org/releases/): authorization failed for https://repo.jenkins-ci.org/releases/org/jenkins-ci/plugins/jackson2-api/2.13.1-246.va8a9f3eaf46a/jackson2-api-2.13.1-246.va8a9f3eaf46a.hpi, status: 403 Forbidden -> [Help 1]

This is a known issue described in the documentation. The recommendation is to

create an issue in the INFRA project on Jira, and let the team know in #jenkins-infra on Libera Chat.

@basil 388 https://github.com/jenkinsci/jackson2-api-plugin/runs/4719142311?check_suite_focus=true#step:4:161 passed and released. I accidentally ran the workflow twice so the second is likely a failure as the artiact already exists and the repo is setup to prevent redeployment. Can you download the artifact from artifactory? On my phone now so can not fully check, or have access to irc

Got it! Yes, looks like it got released at: https://github.com/jenkinsci/jackson2-api-plugin/releases/tag/2.13.1-246.va8a9f3eaf46a
