Add SES6->7 Upgrade Helpers

[tserong]

This adds:

• SES6->7 pre-upgrade checks to the upgrade.status runner (bsc#1174601, bsc#1174605, jsc#SES-1196)
• upgrade.ceph_salt_config, to generate JSON for later use with ceph-salt import
• upgrade.generate_service_specs, to genrate YAML for later use with ceph orch apply
• ceph.upgrade.ses7.adopt state, to be used to run cephadm adopt for core daemons (mon, mgr, osd)

This PR supersedes #1840 which only included the upgrade.ceph_salt_config piece. I've fixed the "time_init: disabled" thing @Martin-Weiss mentioned. I've left the bootstrap_minion in place, because when I last tested this, it seemed ceph-salt still required it (even though it should be optional now) - possibly I did something wrong with my setup, so need to re-test that part.

Aside from the two small issues above, it works for me. It told me to upgrade to SLE15SP2 and ran successfully once I did the above.

There was only one failure - in functional-3nodes. Here is the immediate cause:
