Add a MetadataFile field to BuildOptions, to which we write a dictionary
of information about a just-committed image.
Pay more attention to sourceDateEpoch than to timestamp when we're
tagging an existing image with the intended destination name.

When building or committing an image in OCI format, default to setting
the org.opencontainers.image.created annotation to the value used in the
image's config blob for the image's creation date. The behavior can be
controlled using the new --created-annotation flag.
Add --annotation and --unsetannotation flags to `buildah commit` which
mimic the same flags for `buildah build`.

When using either --source-date-epoch or --timestamp, default to not
adding a label with our version number in it, since it can change
between builds.

Use $SOURCE_DATE_EPOCH as the default for the --source-date-epoch flag
to the "build" CLI.
When a source-date-epoch is set, we'll use it when writing new history
entries, force timestamps in data written for --output to the specified
timestamp, and populate a "SOURCE_DATE_EPOCH" ARG that we treat as
always being set, and which we don't complain about being left unused.
By default, this will not affect timestamps in newly-added layers.
Add a --rewrite-timestamp flag, which "clamps" timestamps in newly-added
layers to not be later than the --source-date-epoch value if the
--source-date-epoch flag is set, but has no effect otherwise.

Add a --source-date-epoch flag, defaulting to $SOURCE_DATE_EPOCH if set,
which sets the created-on date and the timestamp for the new history
entries, but does not default to modifying the timestamps on contents in
new layers.
Add a --rewrite-timestamp flag, which "clamps" timestamps in the new
layers to not be later than the --source-date-epoch value if both
the --rewrite-timestamp and --source-date-epoch flags were set.

Add a --sbom flag to `buildah build` and `buildah commit` which will
scan the rootfs and specified context directories to build SPDX or
CycloneDX SBOMs and lists of package URLs.

Add a flag to `buildah commit` which allows adding arbitrary files to
the image while we're committing it. When not squashing, they'll take
the form of a second new layer.

- remove unnecessary backslashes on underscores
- trim leading spaces on some notes, making them <4.
Too many leading spaces means to format as code.

Add an OverrideChanges and an OverrideConfig field to CommitOptions,
both of which can be used to make last-minute edits to the configuration
of an image that we're committing.

Add docs for the new --cw option recognized by both `commit` and
`build`, and the new `mkcw` command.

Allow end users to remove default identity labels if they want to.
Since there are instances where images can be reproduced across version
hence users must have option to suppress default labels.
