Subject: [PATCH] Reduce max Pulp workers to 12

On seed hosts with more than 32 CPU threads, PULP_CONTENT_WORKERS
and PULP_API_WORKERS were set to 32, which was causing the number
of connections to the bundled Postgres instance to exceed the
default max_connections.

Reducing the maximum number of PULP_CONTENT_WORKERS and PULP_API_WORKERS
will prevent Postgres from running out of connection slots.
