Update Dockerfile curl calls to follow redirects and use new URL
Current https://www.apache.org/dist/cassandra/KEYS URL is a 302 redirect that is not being follows by curl
This is causing errors from apt-key such as Warning: apt-key output should not be parsed (stdout is not a terminal) and gpg: no valid OpenPGP data found.
