Add TAP tests for timeouts

Browse Source 
This commit adds new tests to verify that transaction_timeout,
idle_session_timeout, and idle_in_transaction_session_timeout work as expected.
We introduce new injection points in before throwing a timeout FATAL error
and check these injection points are reached.
