* Replace duplicated empty string arrays with the one in MemoryReductionUtil

* Fix interning where strings are null

* Fix to deal with the fact that we directly mutate dependency fields for UpdateSite, sigh

* Reduce starting HashMap size for some hashmaps likely to be empty or tiny

* Cleanup per review comments

* Trim some extra waste out of the UpdateSite warnings

* Fix count of optional dependencies

* Move predicates for dependency matching to top-level static final field so they are not duplicated

* [JENKINS-31448] Protect against NPE in update center on restart

* rename updateSite private methods

* JENKINS-36547: Introduce Queue.Task.getAffinityKey()

and use it in LoadBalancer.assignGreedily() to find a node for a task.

* JENKINS-53353 Do not cache results of View.getActions()

Plugins that may affect the view, eg via TransientViewActionFactory
that get installed _after_ a `view` has been initally viewed
will not be able to add anything to the view if the results
of getActions() are cached.

* JENKINS-53353 Removed unnecessary synchronization

* JENKINS-53353 Whitespace

* JENKINS-53353 Restored (and deprecated) updateTransientActions

* with PostConstruct method no need to explicitely invoke load() anymore
Signed-off-by: NNicolas De Loof <nicolas.deloof@gmail.com>

* 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.
