Title: ISPN-4950 Add ability to merge defaults into Metadata passed as param

* This is required in order to be able to apply default lifespan and max idle settings configured globally for the cache.
* To do so, a new method has been added to builder that allows a Metadata object to be merged with the builder instance.
* By making the default metadata builder implementation use objects for primitives, it can easily distinguish between those settings that have been set by the user versus the builder defaults.
