    bootstrap_admin_node: Fix connectivity check.

    After Fuel Master builds the bootstrap image at first boot,
    internet connectivity is tested using the URL for the CentOS
    updates repository.

    bootstrap_admin_node.sh script parses the output of `yum repolist`,
    looking for entries like 'Repo-baseurl: http://...'.

    However, in Fuel 9.0, <updates> points to a mirrorlist file (a text
    file containing a list of possible mirror URLs) instead of being
    a single, direct link to the repository.

    For now, we only test that we can access the mirrorlist file,
    while the check should be performed against the mirror(s).

    Old (Fuel 8) repo entry format:
    Repo-baseurl: http://mirror.fuel-infra.org/.../updates/x86_64/

    New (Fuel 9) mirrorlist format:
    Repo-mirrors: http://mirror.fuel-infra.org/.../mos-mirrors-updates.txt
