DAOS-16721 dtx: handle potential DTX ID reusing trouble - b26 #12070

	name: clang-format

	# Report style formatting changes.
	# Run git-clang-format on the contents of the PR against the target commit and display a diff of
	# any recommended changes. Fail the job if any are recommended.
	#
	# Future work would be to have a way to apply these automatically which would require making and
	# pushing a new git commit so should be optional.
	#
	# Runs in a fedora docker container to get a recent clang-format version.
	#
	# This checks out the tree with the default settings - a merge commit of the PR with the target
	# branch, then it applies git-clang-format which only works against branches, not where branches
	# diverge, and then it removes any changes to auto-generated files. The result should be something
	# that can be applied to the PR however it may not apply cleanly if there are merge issues with
	# master - although in this case the PR should be merged with the target before landing in any case.
