Review comment:
I think it's better to catch the problem on master, then send bad input
to the segments and let them find out.
I see nothing wrong with calling literal eval twice--in fact, I think it's
best we interpret the string they pass in the same way each time we process it.
If it's handled one way here, and then another way later, then there are more
possibilities for how the user can insert quotes and other special characters
to confuse MADlib.
However, looking at this again I notice there is a try catch block around
the literal_eval that happens on the segments. If it errors out here, it won't
give as nice a message... so maybe we should add a similar try/catch around it?
