Switching the tier level of a partner tenant

Authenticate to the cloud platform via the Python shell.

The following variables should be available now:

>>> base_url  # the base URL of the API
'https://eu2-cloud.acronis.com/api/2'
>>> auth  # the 'Authorization' header value with the access token
{'Authorization': 'Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsImtpZCI6ImMwMD...'}
>>> tenant_id  # the UUID of the tenant to which the token provides access
'ede9f834-70b3-476c-83d9-736f9f8c7dae'

Assign either of the following values to the tenant_id variable – the UUID of a partner tenant created via the API or a partner tenant found by its name:
```
>>> tenant_id = created_tenant_id
>>> tenant_id
'0fcd4a69-8a40-4de8-b711-d9c83dc000f7'
```
Obtain the list of services enabled for the tenant, which UUID is specified in the tenant_id variable, as described in steps 3-6 of “Fetching information about services enabled for a tenant”. As the result, you should have a tenant_applications variable with the list of service objects.

In this list, find the platform service (the value of a service object’s type key) and store its UUID (the value of a service object’s id key) in a variable named application_id:

>>> application_id = None
>>> for application in tenant_applications:
...     if application['type'] == 'platform':
...         application_id = application['id']
...         break
...
>>> application_id
'6e6d758d-8e74-3ae3-ac84-50eb0dff12eb'

Define a variable named setting_name, and then assign a name of the setting to this variable:
```
>>> setting_name = 'tier_level_value'
```
Define a variable named setting_value, and then assign an object with the value key containing the tier level to this variable:
```
>>> setting_value = {
...     'value': 7
... }
```

Convert the setting_value object to a JSON text:

>>> setting_value = json.dumps(setting_value, indent=4)
>>> print(setting_value)
{
    "value": 7
}

Send a PUT request with the JSON text to the /applications/{application_id}/settings/tenants/{tenant_id}/{setting_name} endpoint:

>>> response = requests.put(
...     f'{base_url}/applications/{application_id}/settings/tenants/{tenant_id}/{setting_name}',
...     headers={'Content-Type': 'application/json', **auth},
...     data=setting_value,
... )

Check the status code of the response:
```
>>> response.status_code
200
```
Status code 200 means that the platform has assigned tenant with the new tenant tier level.

A different status code means that an error has occurred. For the details, refer to “Status and error codes”.

Also, the response body contains the tier level setting object formatted as a JSON text. When converted to an object, it will look as follows:
```
>>> pprint.pprint(response.json())
{'effective': None,
'name': 'tier_level_value',
'own': {'exclusive': False, 'lock': False, 'value': 7}}
```
