FIP: Reduce Storage Limits

@wazzymandias.eth's proposal is up for review. it reduces the # of casts, links and reactions per storage unit to help hubs scale.

"I use all my reaction storage but very little of my cast storage. Can storage units be flexible?"

> Flexible storage units are very tricky to implement with a good UX. There are many problems, but the most pressing one is what to do when you’ve exceeded the limit and send a new message. The only solution with our eventually consistent network is to prune the oldest message, irrespective of type. This means that if you run out of space and like something, the first person you followed may get unfollowed, which is really bad. There is no easy solution to this problem.

If I have 9 storage units and the reactions capacity is reducing from 5k to 4k per unit, will I “lose” 9k storage capacity?
