fix: Pass context all the way down to the network call in lockers (#10161)

Context timeout might race on each other when timeouts are lower
i.e when two lock attempts happened very quickly on the same resource
and the servers were yet trying to establish quorum.

This situation can lead to locks held which wouldn't be unlocked
and subsequent lock attempts would fail.

This would require a complete server restart. A potential of this
issue happening is when server is booting up and we are trying
to hold a 'transaction.lock' in quick bursts of timeout.
