Use a consistent approach for producing warnings, but add a TODO for moving
this warning to the daemon, which can make a better call if it will work
or not (depending on networking mode).
This warning was originally added in [moby@afa92a9], before integration with
libnetwork, and this warning may be incorrect in many scenarios.
While updating, also removing the custom regular expression used to
detect if the IP is a loopback address, and using go's netip package
instead.

This warning was originally added in [moby@3aa70c1], and moved to be printed
on both `run` and `create` in commit 7c514a31c9.
However, [moby@57f1305] (docker 19.03, API 1.40) moved such warnings to
the daemon side. The patch mentioned this issue:
> This patch will have one side-effect; docker cli's that also perform this check
> client-side will print the warning twice; this can be addressed by disabling
> the cli-side check for newer API versions, but will generate a bit of extra
> noise when using an older CLI.
The CLI does not take this into account currently, and still prints warnings
twice; even in cases where the option is not supported by the daemon, and
discarded:
On a host without OomKillDisable support:
docker create --oom-kill-disable alpine
WARNING: Disabling the OOM killer on containers without setting a '-m/--memory' limit may be dangerous.
WARNING: Your kernel does not support OomKillDisable. OomKillDisable discarded.
On a host that supports it:
docker create --oom-kill-disable alpine
WARNING: Disabling the OOM killer on containers without setting a '-m/--memory' limit may be dangerous.
WARNING: OOM killer is disabled for the container, but no memory limit is set, this can result in the system running out of resources.
This patch removes the client-side warning, leaving it to the daemon to
report if any warnings should produced (and the client to print them).
With this patch applied:

This method was a shallow wrapper around registryclient.NewRegistryClient but
due to its signature resulted in various dependencies becoming a dependency
of the "command" package. Consequence of this was that cli-plugins, which

longer used in our code, which constructs the client in packages that need it,

This function was added in 02719bdbb5, and
used newDefaultRepositoryEndpoint to get repository info for the given
image-reference.
newDefaultRepositoryEndpoint uses registry.ParseRepositoryInfo under the
hood, but the only information used from the result was the Name field,
which is set using `reference.TrimNamed(name)`. The possible error returned
was based on the domain-name of the image, and only checked for the domain
to not start, or end with a hyphen ("-").
This patch removes the use of RepoNameForReference, deprecates it, and
inlines the code used by it.
There are no known consumers of this function, so we can consider removing
it in the first possible release after this (which can be a minor release).

These utility functions were added in 8890a1c929,
and are all related to OTEL. The ResourceAttributesEnvvar const defines
the "OTEL_RESOURCE_ATTRIBUTES" environment-variable to use, which is part
of the [OpenTelemetry specification], so should be considered a well-known
env-var, and not up to us to define a const for. These code-changes were not
yet included in a release, so we don't have to deprecate.
This patch:
- Moves the utility functions to the telemetry files, so that all code related
to OpenTelemetry is together.
- Un-exports the ResourceAttributesEnvvar to reduce our public API.
- Un-exports the DockerCliAttributePrefix to reduce depdency on cli/command
in CLI-plugins, but adds a TODO to move telemetry-related code to a common
(internal) package.
- Deprecates the cli-plugins/manager.ResourceAttributesEnvvar const. This
const has no known consumers, so we could skip deprecation, but just in
case some codebase uses this.

[ParseRepositoryInfo] parses an image reference and returns information
about the Repository and the registry. As part of this, it validates if
the registry's hostname is considered valid using [ValidateIndexName],
as well as normalizing the image reference to strip tags and digests
using [reference.TrimNamed].
ValidateIndexName only provides very limited value; the only validation
happening is to check for the hostname to not start, or end with a hyphen.
The cli/command/manifest package used ParseRepositoryInfo in various
locations where only the repository name was used (i.e., the result
of `reference.TrimNamed` on the given reference), and in one location
only used it to validate the registry name.
For buildPushRequest, the call was fully redundant, as [RepoNameForReference]
was used on the result, calling [newDefaultRepositoryEndpoint], which
uses ParseRepositoryInfo internally, so we were only repeating that work.
This patch removes uses of ParseRepositoryInfo in those places, and instead
calling [reference.TrimNamed] directly.

The errors.Wrap and errors.Wrapf functions gracefully handle nil-errors.
This allows them to be used unconditionally regardless if an error
was produced.
While this can be convenient, it can also be err-prone, as replacing
these with stdlib errors means they unconditionally produce an error.
This patch replaces code uses of errors.Wrap to be gated by a check
for nil-errors to future-proof our code.

Remove the `docker.cli` prefixed attributes from
`OTEL_RESOURCE_ATTRIBUTES` after the telemetry provider has been created
within a plugin. This prevents accidentally sending the attributes to
something downstream for the user.
This also fixes an issue with compose where the self-injected `OTEL_RESOURCE_ATTRIBUTES`
would override an existing attribute in the environment file because the
"user environment" overrode the environment file, but the "user
environment" was created by the `docker` tool rather than by the user's
environment.
When `OTEL_RESOURCE_ATTRIBUTES` is empty after pruning, the environment
variable is unset.
