What you wanted to do

use dgraph migrate with a remote mysql server

What you actually did

migrate is hardcoded to localhost

Why that wasn't great, with examples

with the database url being hardcoded to localhost we would have to install dgraph on the mysql server in order to use migrate. My mysql servers are managed and I dont have ssh access. this means I would have to set up a proxy somehow to use the tool in its current state.
