* feat: add pruning of files in WebDAV remote
Based on / Inspired by the minio/S3 implementation of pruning remote files.
* remove logging from the development
* test: first try implementing tests
Sandly I have to use the remote pipeline -- local wont work for me.
* test: adapt used volume names
* test: specify image only once!
* test: minio AND webdav data should be present
* test: backups on WebDAV remote are laying in the root directory
* test: the webdav server stores date in /var/lib/dav
* trying with data subfolder
* test: 1 container was added so the number raised from 3 to 4
* webdav subfolder is "data" not "backup"
* fix: password AND username must be defined
not password OR username
* improve logging
* feat: if the given path on the server isnt preset it will be created
* test: add creation of new folder for webdav to tests

be skipped when pruning. This could lead to a wrong number of candidates
being printed in the log messages.
