How to pause refreshInterval

[SteveSchreiner]

I fetch remote data while setting refreshInterval. I would like the ability to pause refreshing at the set interval. I thought I could do pass a null key but that just cleared the cache all together. My use case is I mutate the data without revalidating and I don't want the interval to fire again and wipe out the data I mutated. As a work around I set up my own timer to refresh at set intervals but it first checks to see if the flag I created to indicate pausing has not been set.
