Issue 51702: Creating new workbooks/experiments is slow

[labkey-jeckels]

Rationale

Creating containers is taking > 5 seconds on servers that have many sibling workbooks/

Changes

• Don't update the max size statistic on caches on every put. Puts can happen many, many times for big caches, and getting the size is expensive enough to add up. We only show the max size in the Admin Console, so it's OK to be a little less granular
• Avoid blowing away the container child cache when the hierarchy hasn't changed

Just FYI: SQL Server JDBC supports LocalDate. That's for another day, of course.
