Request: support enum flags

[gwatts]

Not as neat as the builtin type proposed here, but I implemented something similar using the new(ish) custom type feature https://godoc.org/github.com/gwatts/flagvals#OneOfString

eg.

netMode := flagvals.NewOneOfString("bridge", "none", "container", "host)
netMode.Value = "bridge" // set a default
cmd.Var(cli.VarOpt{
    Name: "net",
    Desc: "Set the Network mode for the container.  Either bridge, none, container or host",
    Value: netMode,
})

Thanks for the feedback.

Good proposal, adding it to the to do list.
