Use shared-secrets.d instead of TailsToaster_config/common.d
We use shared-secrets.d when developing tests, so our isotesters
should use it as well so developers can push updates required for new
tests that will go live on the isotesters as well.
This would also have the advantage of making
tails::jenkins::slave::iso_tester work a bit more out-of-the-box on
other systems than lizard: currently, systems managed by that class get
configuration (e.g. ssh.yml) that can’t possibly work outside of
lizard.
