It would make a lot of sense to add a force run for discovery rules.

Usecase:

I changed a metric (lets say a disk percentage) on a Mounted filesystem discovery rule and would like it to propagate over templates instantaneously rather than the default (60 minutes).

In a large scale systems with many simultaneous changes happening, I'm not going to change the default times lower and higher every time I need to make a change - that wouldn't make any sense, hence it would be a good feature to add.
