Use the same timeout on all tasks related to network patches

[bchamagne]

Description

The network patch calculation takes up to 15seconds in testnet. The timeout values were too low.
This PR calculate the timeout based on the next SelfRepair tick.

In practice, we're setting the timeout to 4m30s instead of 5s.
