Update base docker image to alpine 3.15 (#53)

* add studio-b12/gowebdav to be able to upload to webdav server

* make sure all env variables are present for webdav upload

* implement file upload to WebDav server

directory defaults to the base directory

* docs: add the new feature to the documentation

* if no WebDav env variable are given throw no error

* docs: use more elegant english :D

Co-authored-by: Frederik Ring <frederik.ring@gmail.com>

* docs: use official spelling of "WebDAV"

* perf: golang likes to return early instead of having an else block

* use WEBDAV_PATH instead of WEBDAV_DIRECTORY

* use split_words for more convenience

like shown here: https://github.com/kelseyhightower/envconfig#struct-tag-support

* simplify

* 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

 # docker-volume-backup
 
 Backup Docker volumes locally or to any S3 compatible storage.
 
 The [offen/docker-volume-backup](https://hub.docker.com/r/offen/docker-volume-backup) Docker image can be used as a lightweight (below 15MB) sidecar container to an existing Docker setup.
-It handles __recurring or one-off backups of Docker volumes__ to a __local directory__ or __any S3 compatible storage__ (or both), and __rotates away old backups__ if configured. It also supports __encrypting your backups using GPG__ and __sending notifications for failed backup runs__.
