Unable to create database using IP

[aburhan]

When I run this command

gcloud sql users create $DB_USER
--instance=$DB_HOST \ <--earlier step step DB_HOST to the private IP of the instance.
--password=$DB_PASSWORD

I changed DB_HOST to "menu_catalog" and this step works fine.

@aburhan I've opened PR to switch to INSTANCE NAME - #8

Fixed in #8
