LingxianKong f6a7f2ee2b No input validation for action with kwargs argument
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.
