Warning if using Cloudera Parcels and cores bug

traf_setup: Cloudera parcels are not currently supported by install or
Trafodion core. Because of this an error has been added that will not
allow the user to run trafodion_setup if they have installed via
parcels. This is a temporary fix until parcels are supported.

traf_add_user: Trafodion only supports a max of 15 cores and if more
than 15 cores are detected then the range is changed to 0-15 in the
sqconfig file.

trafodion_setup: Installer verion now included. Hard coded temporarily
until better solution is found.

traf_cloudera_uninstall: Removing yum cache and rebuilding rpm database
during cloudera uninstall.
