Limit the number of prepared statements

Hibernate query statistics are getting flooded with all the variants of a query that uses a parameter list. This makes it very difficult to inspect query metrics exposed by Micrometer.

This can be mitigated by either using fixed size batch or padding to the next power of two.

Another place that is producing a lot of queries is the filtering system in FilteringDao. In #871 we cut that down by querying clauses independently and intersecting the resulting IDs.

This is pretty much completed at this point. I've added a warning with a stack trace when a large number of parameters are passed.
