Request: Online/Offline setup

[JarbasAl]

from a user POV i would expose in the installer, related to https://github.com/OpenVoiceOS/ovos-installer/issues/2 and https://github.com/OpenVoiceOS/ovos-installer/issues/3

Internet capabilites:

• fully offline
  • ensure TTS/STT are on device
  • do not even install skills that require internet
  • main TTS/STT offline
  • ready_settings requires only offline skills to load
• hybrid
  • prefers online usage
  • but will do it's best to work offline (internet considered optional)
  • requires fallback TTS/STT
  • ready_settings requires only offline skills to load
• online
  • best performance
  • absolutely requires internet
  • no fallback TTS/STT
  • ready_settings requires all online and offline skills to load

I'd like to see this as well. Especially to at least be used with the Mark 2. I can't tell you how many times my son and I bought into this robot or that and then they ended up going out of business, bought, etc and then no longer work.
