[doc] Performance benchmark

[the-glu]

In the general context of performance measurement and boundaries, this issue capture the current expected performance for raft and version 0.23.0-rc2.

The following context have been used:

• monitoring's master branch, commit 001de764039cabb3d869b7a9c6a68bce03eac0fd
• DSS Image: interuss/dss:v0.23.0-rc2 for non-raft tests, mcuoorb/dss:raft-1587 based on [raft] Possible optimizations #1587 for raft.
• ran on a dedicated c8id.8xlarge machine.
• NUM_USS="3"
• NUM_NODES="3"
• INTER_USS_NETEM_CONF="delay 16.5ms 7.5ms 50% distribution paretonormal loss 0.025% 25%"
• INTRA_USS_NETEM_CONF="delay 600us 40us 25% distribution normal loss 0.0005%"
• datastore_max_open_conns set to 10

Scenarios from this comment have been reused, with the same parameters.

Could these tests also be run with 7 USSs / 3 nodes each? That's currently our largest pool. Would be curious to see how performance is affected. Thanks!

Yes, I will do as soon as possible. I will also try to find time to make a graph of number of nodes vs performance to see the impact.
