[Epic]: Mint

[tac0turtle]

Summary

With comet completing PBTS we should cleanup and amend the code in the mint module to use time. Along side this we could evaluate any other changes to mint needed.

For time. Currently we use blocks to calculate how much inflation should happen. This is a poor ux because users need to calculate how many blocks they will have in a year and this is influenced by block times.

We should refactor mint to use time, as a factor on how much issuance should be done.

Problem Definition

time is more consistent than block times. Other than that there are features people are wanting out of mint and we should make it easier for them to do it

I dont think mint module is modular, i.e. it doesn't allow people to set custom inflation designs. it only allows users to set how inflation is distributed. I have already talked to users and some have forked mint because of this.

some changes that come to mind are around how inflation is calculated and against what, staked amount or total amount.
