[Core feature] Simplify the local development environment for flyteconsole

### Motivation: Why do you think this is important?

The setup guide of flyteconsole says that we need to generate an SSL certificate and set domain name routing rules in `/etc/hosts`, which is way too complex for frontend development. For the frontend development, we don't need SSL because we can use HTTP instead of HTTPS. We don't need a custom domain name except that the backend has the multi-tenancy feature. However, as far as I know, Flyte does not have the multi-tenancy feature now.

### Goal: What should the final outcome look like, ideally?

Simplify the local development environment for flyteconsole to remove SSL and domain name related stuffs.
