Querying a view with a boolean type key raises a CloudantArgumentError

[rajahaidar]

Bug Description

1. Steps to reproduce and the simplest code sample possible to demonstrate the issue

Create a cloudant database view, and attempt to query the view using the python-cloudant library as follows:

results = database.get_view_result('_design/doc', 'view-name', raw_result=True, key=False)

The above code will raise a CloudantArgumentError due to the validation on this line

python-cloudant/src/cloudant/_common_util.py

Line 192 in 3378146

if (not isinstance(val, RESULT_ARG_TYPES[key]) or

2. What you expected to happen

The expected outcome would be that the view get filtered by the boolean type key instead of raising the error

I removed the validation locally and reinitiated the view query, and the key filtered fine from the CouchDB library end i.e. their library accepted a boolean type for the key argument

3. What actually happened

A CloudantArgumentError was raised when trying to filter by a boolean value for the argument key

Environment details

Python 3.9.2
Database server: IBM Cloudant
