milen 1f237c0aaf borheimdall: only fetch next span when in last sprint of current span (#9096) ... Heimdall prepares the next span a number of sprints before the current span ends. Currently we always fetch the next span regardless of which sprint we are in during the current span. This causes a liveness issue due to how the Heimdall client works (it infinitely retries until it fetches a span - this issue will be fixed in a separate PR). This PR fixes this by matching what bor does - it fetches the next span only in the last sprint of the current span. Changes: - Adds a unit test for the above - Adds a new function BlockInLastSprintOfSpan - Some code reorg and cleanup - moves the span num related functions from the bor package to the span sub package for better logical grouping		2023-12-28 15:52:49 +00:00
