Run Nuxeo from built artifact

As a first step of NMP, we want to run Nuxeo by getting nuxeo-server-tomcat artifact, unzippig it and run it with help of nuxeoctl.

The goal is to create plugin in our repository and to have a base in order to implement everything needed by NXP-26320. We will just take care of running Nuxeo from a Maven plugin.

Plugin location will be in main repository at same level than nuxeo-distribution. As it, users won't need to worry about version of plugin to use, they will just need to follow Nuxeo versions. Furthermore, as the plugin will highly leverage Nuxeo Runtime, this allow us to not have per version conditions in the plugin code.

nuxeo-server-tomcat artifact will be downloaded to target/, unzipped under target/nuxeo-server and then deleted (no issue to do that, there's Maven local repository).
