allow openreview.Client to run as a context manager

1

e.g. ``` with openreview.Client() as client: notes = client.get_notes( ... ) ``` https://jeffknupp.com/blog/2016/03/07/python-with-context-managers/

for Northeastern project

error messages are very uninformative

3

need to refactor the error handling so that the proper error messages are displayed

example: client.get_groups(id="auai.org/UAI/2017/Paper.*/AnonReviewer.*") should return all groups that match the wildcard pattern.
