feat: Name Hasura engine instances

[madmod]

When working with multiple Hasura instances it is difficult to tell which console is for which instance, particularly when using the Hasura cli for migrations as the ports are different. (Eg dev 8080 > cli 8081 and remote 8090 > cli 8091) This problem will only get worse for me as I add more deployment environments and make more products which use Hasura.

It would be great to be able to name a Hasura instance with the cli or environment variables and have that name show in the console ui header and possibly in the logs.
