Update pom.xml to be able to deploy correctly

See the sample POM for new Jenkins plugins: https://github.com/jenkinsci/maven-hpi-plugin/blob/master/hpi-archetype/pom.xml

Skipped upgrading parent pom, as it introduce mandatory FindBugs execution, which fails during the build. I will create a separate issue to fix those #30.
