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
