Prevent potential suggestion when many concurrent requests happen on
the /info endpoint. It's worth noting that with this change,
requests to the endpoint while another request is still in flight
will share the results, hence might be slightly incorrect (for example,
the output includes SystemTime, which may now be incorrect).
Assuming that under normal circumstances, requests will still
happen fast enough to not be shared, this may not be a problem,
but we could decide to update specific fields to not be shared.

- Add the field as a "deprecated" field in the API type.
- Don't error when failing to parse the options, but produce a warning
instead, because the client won't be able to fix issues in the daemon
configuration. This was unlikely to happen, as the daemon probably
would fail to start with an invalid config, but just in case.

The `ClusterStore` and `ClusterAdvertise` fields were deprecated in commit
616e64b42f (and would no longer be included in
the `/info` API response), and were fully removed in 24.0.0 through commit
68bf777ece
This patch removes the fields from the swagger file.

This enables picking up OTLP tracing context for the gRPC
requests.
Also sets up the in-memory recorder that BuildKit History API
can use to store the traces associated with specific build
in a database after build completes.
This doesn't enable Jaeger tracing endpoints from env
but this can be easily enabled by adding another import if
maintainers want it.

The most notable change here is that the OCI's type uses a pointer for `Created`, which we probably should've been too, so most of these changes are accounting for that (and embedding our `Equal` implementation in the one single place it was used).

The existing runtimes reload logic went to great lengths to replace the
directory containing runtime wrapper scripts as atomically as possible
within the limitations of the Linux filesystem ABI. Trouble is,
atomically swapping the wrapper scripts directory solves the wrong
problem! The runtime configuration is "locked in" when a container is
started, including the path to the runC binary. If a container is
started with a runtime which requires a daemon-managed wrapper script
and then the daemon is reloaded with a config which no longer requires
the wrapper script (i.e. some args -> no args, or the runtime is dropped
from the config), that container would become unmanageable. Any attempts
to stop, exec or otherwise perform lifecycle management operations on
the container are likely to fail due to the wrapper script no longer
existing at its original path.
Atomically swapping the wrapper scripts is also incompatible with the
read-copy-update paradigm for reloading configuration. A handler in the
daemon could retain a reference to the pre-reload configuration for an
indeterminate amount of time after the daemon configuration has been
reloaded and updated. It is possible for the daemon to attempt to start
a container using a deleted wrapper script if a request to run a
container races a reload.
Solve the problem of deleting referenced wrapper scripts by ensuring
that all wrapper scripts are *immutable* for the lifetime of the daemon
process. Any given runtime wrapper script must always exist with the
same contents, no matter how many times the daemon config is reloaded,
or what changes are made to the config. This is accomplished by using
everyone's favourite design pattern: content-addressable storage. Each
wrapper script file name is suffixed with the SHA-256 digest of its
contents to (probabilistically) guarantee immutability without needing
any concurrency control. Stale runtime wrapper scripts are only cleaned
up on the next daemon restart.
Split the derived runtimes configuration from the user-supplied
configuration to have a place to store derived state without mutating
the user-supplied configuration or exposing daemon internals in API
struct types. Hold the derived state and the user-supplied configuration
in a single struct value so that they can be updated as an atomic unit.

Passing around a bare pointer to the map of configured features in order
to propagate to consumers changes to the configuration across reloads is
dangerous. Map operations are not atomic, so concurrently reading from
the map while it is being updated is a data race as there is no
synchronization. Use a getter function to retrieve the current features
map so the features can be retrieved race-free.
Remove the unused features argument from the build router.

`docker run -v /foo:/foo:ro` is now recursively read-only on kernel >= 5.12.
Automatically falls back to the legacy non-recursively read-only mount mode on kernel < 5.12.
Use `ro-non-recursive` to disable RRO.
Use `ro-force-recursive` or `rro` to explicitly enable RRO. (Fails on kernel < 5.12)

As of Go 1.8, "net/http".Server provides facilities to close all
listeners, making the same facilities in server.Server redundant.
http.Server also improves upon server.Server by additionally providing a
facility to also wait for outstanding requests to complete after closing
all listeners. Leverage those facilities to give in-flight requests up
to five seconds to finish up after all containers have been shut down.

Fixes `docker system prune --filter until=<timestamp>`.
`docker system prune` claims to support "until" filter for timestamps,
but it doesn't work because builder "until" filter only supports
duration.
Use the same filter parsing logic and then convert the timestamp to a
relative "keep-duration" supported by buildkit.

Commit 3991faf464 moved search into the registry
package, which also made the `dockerversion` package a dependency for registry,
which brings additional (indirect) dependencies, such as `pkg/parsers/kernel`,
and `golang.org/x/sys/windows/registry`.
Client code, such as used in docker/cli may depend on the `registry` package,
but should not depend on those additional dependencies.
This patch moves setting the userAgent to the API router, and instead of
passing it as a separate argument, includes it into the "headers".
As these headers now not only contain the `X-Meta-...` headers, the variables
were renamed accordingly.
