TOMEE-4702 [tomee-10.x]: Drop openejb-common-cli

[rzo1]

Fixes TOMEE-4702.

Stacked on #2934 — please review/merge that one first. This PR is targeted at
the TOMEE-4701-10.x branch, so the diff shown here is only the openejb-common-cli
removal. GitHub will retarget it to tomee-10.x automatically once #2934 merges.

openejb-common-cli is the shared command implementation (deploy, undeploy, list,
classloader, jmx, properties, script, ls, cat, part, help, exit) behind
the OpenEJB remote shell. Its only consumer was openejb-ssh, so once that module is
removed this one is orphaned: nothing else in the tree depends on the artifact, and
nothing references the org.apache.openejb.server.cli package.

Changes

• removed server/openejb-common-cli
• removed the openejb-common-cli module from server/pom.xml

jline:jline and org.codehaus.groovy:groovy-all are kept in the root
dependencyManagement — both are still used elsewhere (tomee/apache-tomee,
tomee/tomee-deb, gradle, and several examples).

mvn validate passes on the full reactor.
