Option to raise exception when unknown parameter passed.

🚀 Feature

Motivation

I'm using papermill to run multiple notebooks. I have a generic .py script with which I pass in the notebook path and the parameter changes which I wish to make. However, in doing so, sometimes, I inadvertently pass parameters not meant for the notebook. I think it would be nice if there was an option to raise an exception if an unknown parameter was passed. I did not spend too much time looking into the code, but I think one just needs to change https://github.com/nteract/papermill/blob/53847310586b74fdb2763fe333ab99babee367ed/papermill/execute.py#L97
