YQL-19747 Introduce SimpleSchemaGateway
Introduce the `SimpleSchemaGateway` to make it easier to implement `SchemaGateway`s. The idea is that actually existing schema providers really do not support filtration such as by name and type, so in practice they return us the whole list and we need to filter it by hand. The `SimpleSchemaGateway` to `SchemaGateway` adapter does this for us -- we only need to implement a path splitting and folder listing.
The other and important feature of the `SimpleSchemaGateway` is that it is simple to implement a caching decorator for it -- just store a mapping `Path -> [FolderEntry]`, while caching a `SchemaGateway` with filters is soooo not trivial.
I also added string constants for known folder entry types, because they should be documented somewhere.
