On chain minting

[renauter]

The time has come to properly do the entirety of the minting on chain
see full specs here threefoldtech/home#1313

This is a huge feature.
Here is a list of TFChain sub issues to be considered to achieve it:

• Minting: create report uptime extrinsic #573
• Minting: track node resources to calculate rewards #574
• Minting: make sure we can calculate su/cu #575
• Minting: track nodes used resources and IP usage + NU #576
• Minting: track farming policies when minting rewards are being calculated #577
• Minting: punish misbehaving nodes #578
• Minting: implement minting calculations #579
• Minting: implement payment trigger #580
• Minting: make sure we can transition from current flow #581
• Minting: some general notes which need some attention #582
• Minting: make periods configurable #583
• Testing

Now that nodes have powerstates and targets we can also take this into account for the minting.

@despiegk what's the plan here? Is this still needed or will that be revisited for 4.0
