Make IPFS daemon run as a process managed by supercluster backend
Update install script to unzip, setup IPFS in a ~/.supercluster dir
Update init logic by making a runtime struct that's composed with the Gin engine
Removed some redundant scripts/logs
Tests
Ensure API works with Postman test collection (n.b. Postman seems to struggle on pinning/unpinning when run from a collection, but the routes work when tested individually. @Kaihuang724 could you check if it works for you?)
