* [JENKINS-53282] "Restarting VM as requested" should be just an INFO message

Previously logged as severe was I think incorrect, as it was simply
reacting on "standard" user interaction.
`INFO` ought to be enough because anyway, that's the default logged level,
hence will still be seen by admins if needed.

Side note: there's clearly duplications of code here.
I might address it later, but do not want to right now transform a 5 min
task into a much riskier one.

* Also lower log severity when shutting down after user request

* introduce PersistentDescriptor to flag Descriptors
which expect load() to be invoked.

This prevent double execution for plugins which
have been designed on previous version of code and
don’t expect load to be automatically invoked.
