Resume Capability for Connection Interruption

[brianhm]

When the Internet connection of the downloading endpoint is interrupted, the binary just bombs out. Can resume capability be added either with a pause timeframe specified as an input switch?

Sounds reasonable, let's look into this!

I am proposing the following:

• Optionally add the --retries flag to specify how many times you want to retry (default: 10)
• Optionally add the --retry-delay flag to specify how long you want to wait in between retries (default: 30 seconds)

Here's sample output for a firmware download:

➜ mist download firmware "Monterey" --force --retries 3 --retry-delay 5
