This release upgrades onlyoffice to v7, adds a seperate postgresdb + rabbitmq
and adds env variables for the forcesave option.

Please add this to your .env file:

```
SECRET_DB_PASSWORD_VERSION=v1

AUTO_ASSEMBLY_ENABLED=false
AUTO_ASSEMBLY_INTERVAL=5min
AUTO_ASSEMBLY_STEP=1min
```

If you like to use the forcesave option, set `AUTO_ASSEMBLY_ENABLED=true`.

Don't forget to generate or insert a new db secret: `abra app secret generate onlyoffice.example.org db_password v1`
