Feature Request

Ionic version:

[x] 4.x

Describe the Feature Request

Please provide the ability to generate a workspace and new libraries and applications within the workspace. I am asking for capabilities equal to "ng generate application", "ng new", and "ng generate library". This would allow people to generate a workspace and multiple projects within the workspace, and shared libraries.
Currently when "ng generate application" is run within an app created with "ionic start" an error is given:

Schematic "e2e" not found in collection "@ionic/angular-toolkit".

No error is given when "ng generate library" is used within an ionic app and code is generated in the "projects" directory, though I am unsure if the code is correct and useful.

Describe Preferred Solution

Either allow "ng generate application" and "ng generate library" to work within an ionic project or create new commands to generate a workspace, library, and sub-application from the ionic cli.
