Subject: [PATCH] Properly set FD_LIMIT in sysv init when installing from
 package on Debian

The default['cassandra']['limits']['nofile'] attribute is not used when
installing from a package on Debian/Ubuntu. This change uses Chef's
FileEdit utility to replace the existing value with the value specified
in the attribute.
