Description

Based on a question in the chat...

JsonMetadataProvider allows us to serialize IHopMetadata objects to a folder in JSON format.
MemoryMetadataProvider "serializes" these objects in memory and can be used for testing.
MultiMetadataProvider allows the mixing of multiple metadata providers so that for example you can inherit from other projects.

Consider splitting up the SDK into multiple pages.
