Cassandra 5 functions

[conorbros]

The only changes are to shotover-proxy/tests/cassandra_int_tests/functions.rs. The rest is from the cluster tests PR.

Javascript functions have been deprecated in Cassandra 5 so I have switched our function tests to Java.

the microbenchmarks have been noisier since #1459 and your PR clearly wouldnt affect them so dont worry about it.

#1468 seems to be a prereq for this PR so I've marked this as draft.

We get to run the whole suite now, nice!
Using java over javascript makes sense to me, no point in testing deprecated features IMO.
