Add an instrumentation for the `ownership` gem. When a transaction is created, if an owner has been set in the gem, use the name of the owner as the namespace for the transaction. Do the same when an owner is set during an active transaction. If more than one owner is set during a transaction, the namespace will be that of the last owner that was set.
