This patch creates rbdmap shell script that is called from init-rbdmap
init script. The patch also renames src/rbdmap configuration file to
src/etc-rbdmap so that rbdmap shell script can be installed via build
system directly. Finally, the patch accomodates these changes in spec
file and build system.
