We make sure they're not hiding at the bottom or in the middle
which makes debugging an utter nightmare!

The API for periodic health checks is repetitive, with a distinct
function for polling a checker to each kind of updater. It also gives
the user no control over the lifetime of the polling goroutines nor
which context is passed into the checker.
Replace the existing PeriodicXYZChecker functions with a single Poll
function which composes an Updater with a Checker. Its context parameter
is passed into the checker and also controls when the polling loop
terminates. To guard against health checks failing closed (ostensibly
healthy) when the polling loop is terminated, the updater is forcefully
updated to an error status, overriding any configured threshold.

Allow health checkers to abort if the request context is canceled.
Modify the checkers to respect context cancelation and return wrapped
errors so the caller of CheckStatus() would be able to discriminate true
failed checks from checks which were aborted because the context became
done.

If the reference in the API request exceeds the threshold allowed by the
reference package (NOTE: this isn't defined by distribution
specification!) we return 500 back to the client.
This commit makes sure we return 400 and the explanation of the error in
the returned JSON payload.

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.
