XD-1509 Exclude projects for maven publish

- Exclude modules and all the hadoop distro subprojects
  - disable maven plugin `install` task

- For `modules` project, make sure the build and lib directories
aren't included as part of the modules' files bundle
ok, I didn't see any issues importing and working with modules/ and other individual modules imported inside eclipse. After confirming that, I went with this route. Let me know if you see any issues with that.
