Teon Banek 5a41478789 Add maintainer scripts for DEB package
Summary:
Add postinst script for DEB package

The script creates a 'memgraph' group and sets permission on installed
'/var/*/memgraph' directories. Only the group is created, while
'memgraph' user is not. It seems more sane only to require group
membership for using memgraph.

Add conffiles for DEB package

This allows for `dpkg` to detect changes in configuration files and
present them to the user. Therefore, we don't need to care whether the
configuration merges are handled correctly nor if we accidentally
overwrite them.

Add postrm script for DEB packaging

The script is only used so that `dpkg --purge` removes '/var/*/memgraph'
directories, even if they contain something.

Add email, longer description and license file to DEB packaging, as well
as a systemd service.

Provide a logrotate configuration and support it in memgraph.

Use DEB package for Docker installation

This way, the whole installation process and testing should go through
DEB.
