Are hosting bonuses occupied forever? #795

Describe the bug

As docs says:

Every hour wts.zold.io server (you can see its source code) selects the best 8 nodes out of those it can see and pays them 1 ZLD, distributing equally. If it can’t find eight nodes, it uses as many as it can find.

https://blog.zold.io/2018/08/14/hosting-bonuses.html

It seems that current situatuion leaves no chance for new node holder to get a payment in a weeks or months. There's number of nodes with score of 100+. Those players blocks others from getting into "top" list. So it seems that there's no way for new node holder to get a reward unless old players leave network.

Probably newcomer supposed to just overwhelm old players with computational power? That's a little bit unclear for now.

My proposal is to make hosting bonuses distribution more encouraging, e.g.:

• reward N top nodes
• also reward M random nodes, excluding top ones

To Reproduce

Steps to reproduce the behavior:

1. Run new node
2. Wait for days
3. Get nothing

Expected behavior

1. Run new node
2. Get a reward in reasonable amount of time
