Bump Ubuntu base image to 18.04

Ubuntu 18.04 has been released. We need upgrade to it this cycle.

Changes made in this patch

- Bump ubuntu repo from xenial to bionic. Some repos do not have bionic
  packages, so still using xenial repos.
- Drop mariadb, percona and nfs-ganesha repo, because these packages are
  already provided by Ubuntu official repo.
- Since qdrouterd does not have bionic repo and xenial packages does not
  work on Ubuntu bionic, just add it into ignore image list.
- Use python-rtslib-fb and targetcli-fb rather than python-rtslib
  and targetcli
- use xen-utils package name rather than with package version one.
- Seems unsigned repo won't work on Ubuntu bionic, stop using infra
  mirrored unsigned repo in gate building job.
