Add script to update sha256 values in data.yml.

Pyyaml really doesn't want to quote some of these values. It still seems to work, though. Here are the commands I used to test locally:

scripts/update_sha.py --path recipes/data.yml --version-major 3.3 --version 3.3.5  --suffix --revision 1
scripts/update_sha.py --path recipes/data.yml --package-name graylog-server --sha256 2939ebb9005d7589cf07e150f897c9fff5c13a7a50e81f7716fffa041aee7b6a
