Install packages only for distros/services.

- We are installing packages only for the services needed.
- We are parsing the packages files and detecting metadatas.
 - If there is a NOPRIME as comment mean we are not doing the install
   just yet.
 - If we have the meta-keyword distro:DISTRO or
   distro:DISTRO1,DISTRO2 it will be installed only for those
   distros (case insensitive).
