Migrating from go-micro v2 to micro v3

[asim]

Hey all

Here's an upgrade guide to go from go-micro v2 to micro v3 https://m3o.org/v2-to-v3-upgrade-guide. This will be useful for anyone who was attempting to run a platform themselves and would prefer that be a complete experience. To those who still want to piece it together, go-micro is probably still your best bet.

Cheers
