Introduce transaction_timeout

Browse Source 
This commit adds timeout that is expected to be used as a prevention
of long-running queries. Any session within the transaction will be
terminated after spanning longer than this timeout.

However, this timeout is not applied to prepared transactions.
Only transactions with user connections are affected.
