Simplify Cassandra server in thread names

[schlosna]

Goals (and why):
Avoid including set of Cassandra proxy addresses in thread names as seen in example:

Atlas getRowsColumnRange 1 rows from namespace.table on CassandraServer{cassandraHostName=cassandra-123.foo.bar, reachableProxyIps=[cassandra-123.foo.bar/127.0.0.1:9160]} worker task-1234 calling cassandra host cassandra-123.foo.bar/127.0.0.1:9160 started at 2022-06-17T12:00:00.123456789Z - 1234567890

Additional follow on to #6076
