Call Home Function (Autosupport)

## Is your feature request related to a problem? Please describe.

When thinking about enterprise storage systems, those systems provide a call-home-function (autosupport) which contains some data about the setup, usage and defects. This `autosupport` function has a defined call home email address and can be setup with additional addresses for customer use. The functionality can be turned on/off, is DSGVO compliant and usually sends collected data once a week.

Taking this as idea, it would be good to have such a function for oCIS too. TBD which kind of data is wanted, but at least if the runtime is used, extensions, file statistics, user statistics, #spaces, #shares etc. This can be completely anonimized if wanted and would help us a lot identifying sweetspots respectively give advices to customers in case of questions.

## Describe the solution you'd like
Implement a data collector and a autosupport functionality

## Describe alternatives you've considered
We do nothing, and guess around

## Additional context
Such data is very important to focus ressources, communication, development etc
