Add a shortcut for --dry-run as -d

[DanielStoehr]

Command

generate

Description

Right now i can run a dry run for generation components/services/etc. with the following command
ng g c mytestcomponent --dry-run

Describe the solution you'd like

i want to generate stuff with a shortcut -d to have a shorter version of it.
(I think in older angular versions it was possible)

Describe alternatives you've considered
