clibase: require structured usage/argument definition #6706
Description
See WIP in clibase-usage.
Essentially, clibase should accept arguments in a way that looks like:
{
"EnumThenSlice",
clibase.Use{
Name: "coder",
Args: []clibase.Arg{
{
Name: "operation",
Value: clibase.EnumOf(nil, "stop", "force-stop"),
},
{
Name: "workspaces",
Value: clibase.StringsOf(nil),
},
},
},
"coder <stop|force-stop> <workspaces...>",
},We should remove the concept a Middleware in addition to this change.
