These will be used in upcoming commits to set specific attributes for
interacting with tunnels.  Since set() will use the key parsing routine, we
also make sure to prepend it with an open paren, for the action parsing to
properly understand it.

nit: I belive the recommended way of comparing types is using
"isinstance":

https://www.flake8rules.com/rules/E721.html

Also, I don't see what can make actmsg be a list. It should always be an
instance of "ovsactions", right?

Yes, you're right.  This was some debug code that I was messing with and
it made it into this submission.  I've dropped it :)  Thanks for the review!
