Fetch information about billing entities

1. Authenticate to the cloud platform via the Python shell.

   The following variables should be available now:

   >>> base_url  # the base URL of the API
   '<the Acronis data center URL>/api/advanced-automation/v1'
   >>> auth  # the 'Authorization' header value with the access token
   {'Authorization': 'Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsImtpZCI6ImMwMD...'}
   >>> tenant_id # the ID of the partner tenant that can be accessed with the token
   'ede9f834-70b3-476c-83d9-736f9f8c7dae'
   

2. Send a GET request to the /BillingEntities endpoint:

   >>> response = requests.get(f'{base_url}/BillingEntities', headers=auth)
   

3. Check the status code of the response:

   >>> response.status_code
   200
   

   Status code 200 means that the request was successful.

   Also, the response body contains the list of billing entities formatted as a JSON text. When converted to an object, it will look as follows:

   >>> pprint.pprint(response.json())
   {
       "entities": [
           {
               "Id": "c4666cb7-ca5f-401d-8ebc-bf58a142b9f1",
