Why does `azd init` only support `--subscription` and not `-s`?

[savannahostrowski]

All the other flags for init support the shorthand flag (e.g. -t, -e) and (e.g. --template, --environment)

For --subscription, we don't seem to support -s. Is this intentional? At a glance, this seems inconsistent.

It was not intentional. We added this flag (as well as location) for use by VS when they ran init (so they could prevent prompting from AZD, back when init asked for these values) and so just having --subscription was fine because that is what VS was coded to use. We will add this back for consistency.

Tong Xu (MSFT) (@v-xuto) can you create a PR for the above -s flag?
