insert_one signature does not match pymongo

[tysonholub]

Some other signatures that do not match:
delete_one: missing let and comment in mongomock
update_one: missing comment in mongomock
find: accepts kwargs in the mongomock signature, but it looks like any truthy kwarg values will raise OperationFailure. comment and max are just a couple I noticed that are not explicitly accepted.

Lines 1032 to 1034 in ae36245

	for kwarg, value in kwargs.items():
	if value:
	raise OperationFailure("Unrecognized field '%s'" % kwarg)
