WIP : APY and Dashboard

[arhamchordia]

This PR majorly contains :

• Dashboard that can visualise historical APYs, TVL and other metrics of pools (this is the main feature we are working on currently)

Side features also include :

• APY fetching into CSV for specific chains, protocols and denoms
• Historical APY fetcher for any pool listed on defillama

To test :

1. Run python3 db/api.py
2. Run cd dashboard && npm run dev

Please clean up first, i.e. remove all files that should not be part of that and remove all redundant comments.
Then split this into 2 PRs, one for the boilerplate, one with the actual code

Please clean up first, i.e. remove all files that should not be part of that and remove all redundant comments. Then split this into 2 PRs, one for the boilerplate, one with the actual code

Please try running this first as instructed in the description and provide feedback on that. PR is still a work in progress, cleanup can be done later.
