Use --rows-per-insert instead of merge_inserts.awk

Older versions pg_dump didn't have this option so we had to use
our custom AWK script to get a significant speed-up of loading
dumps from feeders on a superhub. All versions of PostgreSQL
CFEngine Enterprise is shipped with now have pg_dump supporting
the new --rows-per-insert option.

Changelog: Data dumping on Federated Reporting feeders no longer
           uses an AWK filter to merge INSERT lines in the dumps
Ticket: None
