This commit refactors the GCS storage driver from the ground up and makes
it more consistent with the rest of the storage drivers.
We are also fixing GCS authentication using default app credentials:
When the default application credentials are used we don't initialize the
GCS storage client which then panics.

the `uuid` package is not used in the code base,
so it can be safely remove.

For some reason a PR we merged passed the build even though it was
missing various func parameters. This commmit fixes it.

This go.mod was used to allow vendoring the docs with Hugo, but this
was never used, so we can remove the go.mod altogether.

Several storage drivers and storage middlewares need to introspect the
client HTTP request in order to construct content-redirect URLs. The
request is indirectly passed into the driver interface method URLFor()
through the context argument, which is bad practice. The request should
be passed in as an explicit argument as the method is only called from
request handlers.
Replace the URLFor() method with a RedirectURL() method which takes an
HTTP request as a parameter instead of a context. Drop the options
argument from URLFor() as in practice it only ever encoded the request
method, which can now be fetched directly from the request. No URLFor()
callers ever passed in an "expiry" option, either.

The specifics of how the authorization for a request is propagated
through the registry app are private implementation details. Hide those
details from outsiders so they can be changed as needed without fear of
breaking third-party code. Move the utilities for attaching a request's
authorization status to its context and retrieving it from the context
into the registry/handlers package as unexported symbols.

The details of how request-scoped information is propagated through the
registry server app should be left as private implementation details so
they can be changed without fear of breaking compatibility with
third-party code which imports the distribution module. The
AccessController interface unnecessarily bakes into the public API
details of how authorization grants are propagated through request
contexts. In practice the only values the in-tree authorizers attach to
the request contexts are the UserInfo and Resources for the request.
Change the AccessController interface to return the UserInfo and
Resources directly to allow us to change how request contexts are used
within the app without altering the AccessController interface contract.

The RemoteAddr and RemoteIP functions operate on *http.Request values,
not contexts. They have very low cohesion with the rest of the package.

Our context package predates the establishment of current best practices
regarding context usage and it shows. It encourages bad practices such
as using contexts to propagate non-request-scoped values like the
application version and using string-typed keys for context values. Move
the package internal to remove it from the API surface of
distribution/v3@v3.0.0 so we are free to iterate on it without being
constrained by compatibility.

This commit make the S3 driver chunk size constants more straightforward
to understand -- instead of remembering the bit shifts we make this more
explicit.
We are also updating append parameter to the `(writer).Write` to follow
the new convention we are trying to establish.

Nowadays there are much, much better UUID implementations to choose
from, such as github.com/google/uuid. Prevent external users from
importing our bespoke implementation so that we can change or migrate
away from it internally without introducing breaking changes.

Our registry client is not currently in a good place to be used as the
reference OCI Distribution client implementation. But the registry proxy
currently depends on it. Make the registry client internal to the
distribution application to remove it from the API surface area (and any
implied compatibility promises) of distribution/v3@v3.0.0 without
breaking the proxy.

docker/libtrust repository has been archived for several years now.
This commit replaces all the libtrust JWT machinery with go-jose/go-jose module.
Some of the code has been adopted from libtrust and adjusted for some of
the use cases covered by the token authorization flow especially in the
tests.
