1. sql: bump default value for sql.stats.persisted_rows.max …

   Previsouly, sql.stats.persisted_rows.max has a default value
   of 10,000 rows. This is significantly lower than even the
   in-memory fingerprint count limits (100,000 entries).
   This commit bumps the default value for sql.stats.persisted_rows.max
   to 1,000,000 rows. With average row size = 1 KiB, this is equivalent
   of 1 GiB limit for system.statement_statistics and
   system.transaction_statistics tables respectively.
   
   Release justification: Bug fixes and low-risk updates to new
   functionality
   
   Release note (sql change): sql.stats.persisted_rows.max's default
   value is now 1,000,000.
