Benchmark Improvements

[jeremyprime]

Changes:

• Fixed GLIDE JDK requirement (needs JDK 11, otherwise will fallback to Gradle toolchain which calls Foojay Disco API, which frequently is not available causing CI to fail)
• Added server topology mode option (standalone or cluster, defaults to standalone)

Note that I also tried to add 100-client workload, but it timed out after 30 minutes. Seems that resp-bench BenchmarkEngine.createClients creates a separate GLIDE client per connection, which works for other drivers including spring-data-valkey, but not for GLIDE itself when tested as the primary driver.
