v.1.2.0 - New User Management, MQTT DataTarget, Improved LoRaWAN Monitoring, General fixes

Important notes on migrations

New User Management
This release fundamentally changes how useraccess is managed in OS2iot. A database migration automatically maps the existing UserGroups/Permissions to the new models - but as these cannot be mapped exactly 1:1 you should check out the mapping before releasing and manually correct issues. The new structure is documented in:
https://os2iot.readthedocs.io/en/latest/software-architecture/software-architecture.html?highlight=Gateway%20administrator#user-permissions

Emails
As a new feature, the platform can and will now send emails to new users and User Administrators when applying for access to organizations. This requires the setup of new environment variables in the backend as described:
