openshift test plugins should be runnable as packaging=eclipse-test-plugin, not eclipse-plugin

Currently, org.jboss.tools.openshift.express.client.test and org.jboss.tools.openshift.egit.test are set to packaging=eclipse-plugin via their pom.xml files.

In order for these plugins to be RUN as tests, rather than just COMPILED as plugins, you need to change them over to packaging=eclipse-test-plugin.

Please make this change, then build locally to ensure your tests actually run w/o failure.

Then, once committed, you can verify they're run here:

https://hudson.qa.jboss.com/hudson/job/jbosstools-3.3_trunk.component--openshift/

You will see that currently there's only one test being run there:

https://hudson.qa.jboss.com/hudson/job/jbosstools-3.3_trunk.component--openshift/lastCompletedBuild/testReport/org.jboss.tools/NoTestsRun/NoTestsRun/

(That's a fake test that is just there so that Hudson will always have at least one test to parse into test results for every job. When you have real tests running, you'll see there will be more than just the single fake test shown.)
