Polish Cassandra health auto-configuration

The indicators that require Spring Data were removed. This commit
updates the auto-configuration ordering as there's no longer a need
for Spring Data Cassandra to have been auto-configured first. It also
simplifies the tests as Spring Data no longer needs to be considered.

Closes gh-45585
