[libvirt] [PATCH rust 4/5] switch to the last ubuntu lts bionic

[Sahid Orentino Ferdjaoui]

Not sure what the problem is by using 'scram-sha-1' with ubuntu:

cannot list SASL mechanisms -4 (SASL(-4): no mechanism available:
Internal Error -4 in ../../lib/server.c near line 1762)

So we currently switch the mech to digest-md5. Seems that libvirt-go
is doing same.
