[full-ci] enhancement: handle ocm event notifications

[fschade]

Description

By now, the sciencemesh part in reva was responsible to notify the invitee that a invitaion happened, in ocis we have a event driven approach.

Yes, that would be awesome!

@fschade Pls check if the audit services also contains translation relevant end user strings (not log stuff). In case, you need to have a look at https://owncloud.dev/services/general-info/add-translations/ for a how to. This includes the translation setup and the readme addition.

Pls also have a look at the admin docs Email Notification Templates respectively in the corresponding notification readme if we are missing anything regarding email templating
