its GetMetadata method called to create its metadata rather than having
its properties scanned.
Added tests for the IMetadataProvider
Merge pull request #519 from kcuzner/attributed-multivalue

Attributed Metadata allowing overriding of metadata creation via an IMetadataProvider interface on metadata attributes
Updated Autofac.Extras.Attributed version
Added API doc for attributed metadata
Added docs for component resolution
Updated Attributed requirements to core 3.4.0

Due to some assembly versioning issues, the released version of the
attributed assembly depends on Autofac v3.4.0 but the NuGet requirements
didn't line up. This addresses that issue.
