It seems that record deletions can cause extreme slowdowns for Koha
installations with extremely large numbers of records. It would be
helpful to be able to skip record deletions when processing the
zebraqueue with rebuild_zebra.pl so the deletions can be processed with
a lower frequency.
Test Plan:
1) Disable any zebra indexing cronjobs you may have
2) Delete a record
3) Note the operation recordDelete in the zebraqueue table having done = 0
4) Run misc/migration_tools/rebuild_zebra.pl -b -z --skip-deletes
5) Note the delete still has done = 0
6) Run misc/migration_tools/rebuild_zebra.pl -b -z
7) Note the delete now has done = 1

Passes all tests and QA script.
Also tested for authorities, no problems found.

RM note: this is at best a work-around, and I will emphasize that
--skip-deletes should be used only when absolutely necessary.
I hope that --skip-deletes can go away at some point soon, but
that may depend on changes to Zebra.
