dogshell and dogwrap dont support ddgov and ap1 sites

Is your feature request related to a problem? Please describe.

dogwrap and dogshell cli tools validate api_host and region arguments from a list of regions. today they only accept us, eu, us3, and us5. its not possible to specify us-fed1 or ap1 via the --site or --api_host arguments. It does appear to work though if you set api_host in dogrc though.

Describe the solution you'd like
It should be possible to specific AP1 or US-FED1 as targets for event/metric submission when using dogshell and dogwrap.

Describe alternatives you've considered
It does appear to work though if you set api_host in dogrc though.
