In Mistral, there may be a lot of native actions registered in the system, e.g. std.echo, std.http, etc. However, not all of them have precise parameter definition in their initialization, Nova action 'servers.find' is a typical example of this. This patch add name of the ** argument in action definition input string, in case there is no other explicit positional params, we don't check action input if it has ** argument. Note: We don't support only *args argument contained in action initialization for the time being, since the type of default action input is dictionary.
