Convert to Nx Plugin

[NetanelBasal]

Advantages

• We could leverage the "preset" option to cover the initial generation of the workspace.
• Instead of workspace-generators, have them as proper generators of the plugin.
• Make it configurable, for example, allowing define the application name on creation.

Disadvantages

• Contributing will be more challenging as we first need to create the workspace, make the changes, and copy-paste it into here.
