feat: add support for docker images (#2714)
* feat: add support for docker images

Issue #724

A new config section under "HTTP" called "Compat" is added which
currently takes a list of possible compatible legacy media-types.

https://github.com/opencontainers/image-spec/blob/main/media-types.md#compatibility-matrix

Only "docker2s2" (Docker Manifest V2 Schema V2) is currently supported.

Garbage collection also needs to be made aware of non-OCI compatible
layer types.
