[PATCH] ctdb-client: Increase the timeout for TRANS3_COMMIT control

On a busy system, TRANS3_COMMIT control can take upto or longer than
3 seconds. On timeout, there are few possible outcomes.
1. The transaction has completed on all nodes and TRANS3_COMMIT control
has returned. In such a case, there is no problem.
2. The transaction has completed on the local node, but TRANS3_COMMIT
control is still active. In such a case, ctdb_transaction_commit()
can return successfully. If this is being called from ctdb, then
ctdb will exit. This will cause ctdb daemon to trigger recovery
since the client exited while transaction is active. This will cause
3. Database recovery was started and ctdb_transaction_commit() will
retry till the recovery completes the transaction.
Increasing the timeout to 30 seconds will avoid the spurious database
recoveries when TRANS3_COMMIT control takes longer to finish.
Please review and push.
