[mysql-8.0 backport]

When setting up a new server in order to add it to a existing group,
one of the main pain points in this process is provisioning the new
server. In order to improve this experience this worklog aims to make
use of the MySQL clone plugin, integrating it with Group Replication
to turn this process less cumbersome.

The end goal of this process is that the user can start the group
replication process in a new server and automatically it will clone
the data from a donor and get up to speed without further
intervention.
