✨(backend) profile api using django-silk

Browse Source 
We have performance issue with the media_auth endpoint. We need to
monitor and profile this endpoint to understand what is happening. We
decided to install and configure django-silk. By default django-silk is
not enabled and not accessible, once enabled migration must be run and
the /silk/ endpoint will be accessible only using a super user.
To have relecant profiles and monitor we must have a database comparable
to a production one because we are facing a scaling issue. Unless a
million documents probably nothing is happening, for this we added
several management commands to help us. A first one to anonymize a
database than can be reused without any risk to leak PII data, can be
called using python manage.py anonymize_database with some mandatory
options. An other command to generate a database profile, this command
should be run on a production database, this profile can then be used by
the generate_volumetry to populate a development database with same
volumetry than describe in the profile.
