Add a functional argument to pass a digest to (ManifestService).GetByTag().
If the digest matches an empty manifest and nil error are returned.

Challenger manager interface is used to handle getting authorization challenges from an endpoint as well as extracting challenges from responses.

Replace ping logic with individual functions to extract API version and authorization challenges. The response from a ping operation can be passed into these function. If an error occurs in parsing, the version or challenge will not be used. Sending the ping request is the responsibility of the caller.
APIVersion has been converted from a string to a structure type. A parse function was added to convert from string to the structure type.

Timeouts should not be a discrete period of time, because they end
up being arbitrary and may be difficult to gauge correctly against
very large Docker layers. Rather, timeouts should be set at the
transport level using the SetDeadline attribute on a net.Conn
object.

To make the definition of supported digests more clear, we have refactored the
digest package to have a special Algorithm type. This represents the digest's
prefix and we associated various supported hash implementations through
function calls.

The change relies on a refactor of the upstream resumable sha256/sha512 package
that opts to register implementations with the standard library. This allows
the resumable support to be detected where it matters, avoiding unnecessary and
complex code. It also ensures that consumers of the digest package don't need
to depend on the forked sha implementations.
We also get an optimization with this change. If the size of data written to a
digester is the same as the file size, we check to see if the digest has been
verified. This works if the blob is written and committed in a single request.

Changes behavior so ping doesn't happen if /v2/ is anywhere in a request path, but instead only at the beginning. This fixes attempts to ping on redirected URLs.

Repository creation now just takes in an http.RoundTripper. Authenticated requests or requests which require additional headers should use the NewTransport function along with a request modifier (such an an authentication handler).
