Mediatype changed to application/tar+gzip. Please see the
following OCI mailing list item for more info:
https://groups.google.com/a/opencontainers.org/forum/#!topic/dev/pdc1lucm_Ak
Also, improved check for invalid manifests, a nil reference error was
occurring when upgrading from existing cache with old mediatype.

No more magic separating the metadata from chart tarball - charts are
pushed to registry as a single tarball layer with Chart.yaml in tact.
No more fragile custom symlink chart storage, now following
the OCI Image Layout Specification for chart filesystem cache.
Also:
- Update to ORAS 0.6.0
- Simplify registry client setup with NewClientWithDefaults()
- Remove needless annotations and constants
