Bug 1129 - POM Versioning changes for automated weekly releases -  Moved all ommon third party dependencies to odlparent

${nexusproxy} variable does not get replaced after introducing odlparent. This is a known bug in maven 2 & 3 where property replacement does not work reliably.

As a workaround, I had to use complete url for nexus in repository and distribution management sections.
