Error if required schematic properties without defaults are not provided

[dansanderson]

Currently if a schematic property is in schema.json's "required" list, nothing different happens if the option is not provided on the command line and doesn't have a "default". It should report a user error in this case.

I was just about to report this. It works fine for me if the schematic is run with the "schematics" tool. However, if the schematic is run from "ng" it ignores required properties.

schematics @Mystuff:myschematic <-- throws error if required prop not specified

ng g myschematic --collection @Mystuff <-- ignores required props

IMO, this is a BUG and not a feature request.
