[FEAT] Multitoolbox Benchmarking

Is your feature request related to a problem? Please describe.
Multitoolbox additional feature. For user that want to check if their machine passes the Flux benchmarks need to go to the Testnet and go through that process. That process entails quite a lot of steps just for a quick test. What i mean by that is they will need to:

1. Install old Zelcore
2. Request coins
3. Go through the very long daemon synch as there is no chain download (thus getting longer and longer)

for a user that just want to see if their hardware is sufficient that is a lot of steps. Ontop the section in the official guide:

The sysbench results in the guide no longer reflect accurate benchmark score any more. Ontop the script is slightly incorrect "--" instead of "-'

Describe the solution you'd like
Option 16 that will download sybench and perform the exact same benchmark Flux performs and shows results without going through the whole testnet

Describe alternatives you've considered
Performing testnet and
