What this PR changes/adds

adds asset mgmt api v4alpha.

Since it's the first PR after introducing the #5153 it does not contains only asset v4alpha controller but also additional
implementations for:

• Supporting optional validation on the input object before expansion in JerseyJsonLdInterceptor (used for v4 controllers)
• For backward compatibility with current controllers, a JerseyJsonLdInterceptor is registered a dynamic resource on each controller of the mgmt API v3
• Introduced a SchemaType annotation that should be used to annotate the expected schema of an input JsonObject
• Add missing CatalogAsset type in JSON-LD context and JSON-schema
• For now the old validation on expanded object is still in place for Asset type. It will get removed once the schema validator is bundled in the management api (currently an add-on extension)

This is marked as breaking-change since it requires to register a JerseyJsonLdInterceptor for custom controllers.
