Reinvent current bounty structure

[yangwao]

I would invite all past, current and future participants who've made their PR to our codebase and get paid in KSM.

With upcoming events, we expecting scaling up our operations around KodaDot much further than used to be.
My previous structure, flow, processes we're based on my best guess and I guess it's around clock to adjust them from v0 to v1 to be more streamlined, more autonomous, less heavy on attention and important way more pleasure and rewarding adventure for existing and incoming participants as KodaDot is gaining traction and momentum with every day :)

Here is what I would like to solve is

• bit adjust even if so $ reward labels, rewards to reflect the complexity of changed or added new code
• flex payment process - probably looking forward if we can come up with some lean GH app to process payments
• someone who would be in charge of reviewing PRs, collecting feedback from newly opened issues, in some cases making quality replies, which might push the product to the desired way
• most importantly, hear your feedback what was pain issues, what kind of soft skills we should play much better, what's our current weakness, &c
• what should be added to CONTRIBUTING.md

I'll try to reply async as possible when time allows for each comment.
