Problem Description

Currently, TheHive4Py allows basic authentication only. And since TheHive 2.13.0 will provide the ability to call the APIs using an API Key, we need to support this type of authentication mechanism to TheHive4Py library, without breaking the basic authentication support that already exists.

[nadouani]

This change doesn't break the existing instantiation style of TheHiveApi class. Developers can now use one of the following ways:

• Using username and password (Deprecated method)

api = TheHiveApi('http://127.0.0.1:9000', 'USERNAME', 'PASSWORD')

• Using API KEY (Recommanded method)

api = TheHiveApi('http://127.0.0.1:9000', 'API_KEY')
