Amplify-cli: Add a way to use human-readable names for resources

Is your feature request related to a problem? Please describe.
It's challenging when the amplify cli creates resources named like "cognito1eb8d495_userpool_1eb8d495". At a glance, it's impossible to tell which app it belongs to, whether it's staging or production, etc.

Describe the solution you'd like
The CLI should have a way to set a prefix, e.g. amplify add auth --name-prefix my-app-dev- or something similar to this.

Stack names could use some tidying up too IMO:

These are different environments too, so it would be nice to see amplify-vue-dev or amplify-vue-prod (amplify-vue is the name of my project).

Thanks for your feedback @ffxsam. We'll work on getting these names friendly.

Having the ability to choose your own resource name like amplify add api would be a welcomed addition.

Or the ability to change the user pool title in the dashboard.

@ffxsam We've fixed both the issues that you'd mentioned. We use the project-name as the prefix for your Cognito userpools now and also use the env-name as a part of your cloudformation stacks. Please use the latest version of the CLI and let us know what you think about it.
