Indent "Workload ID aliases:" header

[BretJohnson]

The workload ID options appear to be be duplicated in the usage message below. At least, that's what I thought at first before realizing that they apply to the install and run commands separately.

I think it may look better adding 6 spaces indent before the Wordload ID aliases: header text, so it's indented the same as the other options. That way it doesn't appear like the a separate group.

You could also move the workload IDs to a separate section, and no longer list twice, but I think the indent is probably enough here.

Usage: vs [command] [options]

Suggestion to indent the worload Id header by 6 spaces seems the easiest and effective way to improve this
