Adds crane.Rebase helper function for higher-level functionality including annotation-based hints

With this change, crane rebase <image> without args will attempt to determine the old and new base from (WIP placeholder) annotations, perform the rebase, and push a new image back to <image> (--rebased flag will override). The rebased image will have base-by-digest and base-by-tag annotations added for future rebase operations.

  • --original if provided overrides the positional arg
  • --old_base and --new_base override any detected annotations
  • --rebased (deprecated, now --tag to match other surfaces) overrides pushing over the original image
  • base-digest and base-tag annotations are populated from --new_base by digest+tag (or previously detected base-tag)

This is WIP while we sort out whether the annotation will be a reserved annotation in the OCI spec. If the code looks good, I'll take a stab at updating rebase.md as well (it could probably use it anyway 😅 ).

Implement annotation-based rebase hints
b27d11c 
`crane rebase` now inspects the original image for annotations to
identify its old base and new base images. If those are found, and
--old_base and --new_base flags aren't specified, those will be used.

If the --rebased flag is not passed, the rebased image will be the
tagged with the original image reference; if it was originally specified
by digest, the rebased image will be tagged with :rebased (instead of
stripping the digest and pushing to :latest)

`crane rebase` now prints the full pushed image reference, instead of
just the digest (aiding embedding in other bash pipelines), and adds
annotations to aid future rebasings.

This also adds a bash test that covers the rebase case for detected base
image information.

Thanks. I still need to hook it up into CI tests...

Wanna do that? If not, ready for final review?
