Added
- Priority queue now blocks by default when the value returned is
empty. This can be disabled by setting the input parameter
`DynamicPriorityParameter.blocking` to `False`.
- Capacity distribution weight parameters can now be scheduled
- Riberry will track `READY` and `ACTIVE` execution task IDs in Redis.
If these executions are still marked as `READY` or `ACTIVE` but their
task IDs don't exist in Redis anymore, the execution is cancelled due
to the assumption that Redis itself was flushed and all progress for
that execution was lost.
Fixed
- Application instance schedules now accept `0` as a valid value
