This CL provides minimal `git cl format` support to enforce correct Rust
formatting in presubmit checks. For now the files are always fully
formatted - there is no support at this point for formatting only the
changed lines.
Manual tests (after temporarily, artificially introducing a formatting
error to one of .rs files under build/rest/tests):
*) git cl presubmit
Result: The src directory requires source formatting.
Please run: git cl format
*) git cl format --dry-run
Result: Pretty/colorful diff printed out.
*) git cl format
Result: Temporary formatting errors are fixed.
