Argh crap camel-blueprint has some complex logic for its property placeholder -
so its getting harder to refactor
> PropertiesSource to resolve a single property

> Key: CAMEL-13708
> URL: https://issues.apache.org/jira/browse/CAMEL-13708
> Project: Camel
> Issue Type: Improvement
> Components: camel-core
> Reporter: Luca Burgazzoli
> Assignee: Claus Ibsen

> Fix For: 3.0.0

>
> CAMEL-13705 introduces support for property sources such as MP Config and
> others and at the moment it does require to load all the properties upfront
> on source initialization.
> It would be nice to have an additional method to resolve a single property as
> some back-and may perform some I/O to resolve properties and get alll of them
> could be expensive.
> So the properties component should:
> - leverage PropertiesSource::loadPropertiers() when is is required to know
> all the properties (i.e. when auto configure components in camel main)
> - leverage a new PropertiesSource::resolveProperty(String) when it just need
> to resolve a single property
