- Perform feature detection when actually needed, instead of during
initializing
- Version negotiation is performed either when making an API request,
or when (e.g.) running `docker help` (to hide unsupported features)
- Use a 2 second timeout when 'pinging' the daemon; this should be
sufficient for most cases, and when feature detection failed, the
daemon will still perform validation (and produce an error if needed)
- context.WithTimeout doesn't currently work with ssh connections (connhelper),
so we're only applying this timeout for tcp:// connections, otherwise
keep the old behavior.
