nova-grenade-live-migration job failing on ubuntu bionic due to missing ceph package

Looks like we should be getting it from luminous:

http://download.ceph.com/debian-luminous/dists/bionic/

(12:23:54 PM) coreycb: mriedem: hi, we have luminous in our bionic /queensrepos

The following looks like an error from atp:

10:59 AM E: Failed to fetch http://download.ceph.com/debian-hammer/dists/bionic/main/binary-amd64/Packages 404 Not Found [IP: 2607:5300:201:2000::3:58a1 80]

Can you just pick up ceph from ubuntu repos? For example, from /etc/apt/sources.list:

deb http://us.archive.ubuntu.com/ubuntu/ bionic main restricted

s/atp/apt

It also looks like this should have already setup devstack-plugin-ceph to support bionic:

It's also failing in the nova-live-migration job so it's not about grenade, it's about the script at nova/tests/live_migration/hooks/ceph:

As a workaround the ceph part of the nova live migration post-test-hook is being disabled.

    Skip the ceph based live migration testing

    While moving the legacy jobs on Bionic[1], it is found
    that ceph pckg hammer is not available to download
    on bionic and it error with 404. Due to that job testing the
    live migration on ceph not working:
    - nova-live-migration skip the ceph live migration testing[2]
    - nova-grenade-live-migration fail due to no ceph pckg[3]

    To proceed further on Bionic migration which is blocked by these failure,
    this commit temporary skip the ceph live migration testing until
    bug#1819944 is fixed.
