Extract BenchmarkConfig from Benchmark

[jamesmarkchan]

It is best to extract benchmark configuration out of the benchmark.

the benchmark configuration could have a copy of the BenchmarkProfile.

Benchmark would have underneath it:

1. Start and end time
2. BenchmarkConfig > container benchmark profile or attributes contained in the profile.
3. SystemInformation (this could be part of config)
4. Operations

public class BenchmarkConfig {
    
    private BenchmarkProfile profile = null;
    
    public BenchmarkProfile getProfile() { return profile; }
    public void setProfile(BenchmarkProfile profile) {
        this.profile = profile;
    }
    
    // Additional run-specific metadata
    // relocate from the Benchmark class here, everything but results
}

This would affect the backend schema and any code that reads the benchmark datamodel.
