Merge ~sylvain-pineau/plainbox-provider-checkbox:add-systemd-analyze-cert-parts into plainbox-provider-checkbox:master

[Sylvain Pineau]

Add info/systemd-analyze to also gather bootup metrics for classic.

Added as an extra mandatory job in submission-cert-full instead of just another depends in misc/submission-resources as it can easily fail if some systemd units are blocking the desktop targets.

e.g:

$ systemd-analyze
Bootup is not yet finished. Please try again later.
