Docker Official Image:
- The following changes have been made to the docker.io/library/mariadb container image.
- The number of gpg packages packages has been removed, leaving enough to apt-get update, but dirmngr that would fetch keys has been removed. (inspired by issue #469)
- The environment variable LANG=C.UTF-8 has been added for those that exec into containers and copy paste UTF8 characters (fixes issue #468).
- Adds OCI labels to image (fixes issue 436 and users need for version)
- MariaDB config: skip-host-cache and skip-name-resolve moved to /etc/mysql/mariadb.conf.d/05-skipcache.cnf
