Add rpm packaging for openflowjava and openflowpluging to buildrpm.sh.

Add rpm packaging for openflowjava and openflowpluging to buildrpm.sh.

- remove tabs in buildrpm.sh (for real this time)
- Added openflowjava and openflowplugin to buildrpm.sh
- Reworked projects to use arrays so it is easier to add new projects in the future.
- Added mockmvn option to allow rewriting the maven command used when mock builds the rpms. This is useful to allow specifying a local .m2 cache so moc
k does not clean and reinstall between every build.
- ensure git version tags are used throughout for all projects. This ensures the src.rpm files are marked with consistent git hashes for easier reprodu
cing of a build.
- Cleaned up distribution.spec Requires to not require controller-dependencies since it is Required by the controller already.
- Removed duplicate code in dependencies.spec.
