Increase the number of ALTER TABLE operations that can be performed online without placing the table in "reorg pending" state

ADMIN_MOVE_TABLE should immediately fail or at least warn when source table is ineligible for SWAP

Number of Occurrences for Alert

Add microseconds to the Db2 pureScale log timestamp to match what Db2 z/OS is doing today.
