[deployment examples] simplify traefik configuration

[wkloucek]

Description

• Simplifies the deployment example by using a global http to https redirect.

During testing and changing the configuration a few things popped up and have been fixed / changed, too:

• Removes the "owncloud10_with_oc_web" example. This is outdated since we have the ownCloud Web app for ownCloud 10 and the Web sidecar docker image (https://hub.docker.com/r/owncloud/web). Parts of the example have been prepared to demonstrate the migration, but it was neither working nor documented. An migration example will be added in add migration deployment #2302
• fix login with ldap example by setting the cn to the username
• remove idp from the keycloak example because it will never be used in that case
• fix access to the minio console in the S3 example deployment

Related Issue

• none
