Add support for --jobs in reindexdb
When doing a schema-level or a database-level operation, a list of
relations to build is created which gets processed in parallel using
multiple connections, based on the recent refactoring for parallel slots
in src/bin/scripts/. System catalogs are processed first in a
serialized fashion to prevent deadlocks, followed by the rest done in
parallel.
This new option is not compatible with --system as reindexing system
catalogs in parallel can lead to deadlocks, and with --index as there is
no conflict handling for indexes rebuilt in parallel depending in the
same relation.
