Ensure Ferrum could Handle 10K users with N users works simulteniously

[EvilLord666]

We should Create scenarios to test performance of Ferrum Authorization Server as follows:

1. 10K users in Redis separated:
   • by 100 users in 100 Realm
   • by 1K users in 10 Realms

Scenarios will be developed with K6S and include:

1. Issue new token
2. After 1-2 s call UserInfo endpoint 5 times with interval 1-2 second each
3. Call Token Introspect (optionally)
4. Wait 60-120 s and do the same in 2
5. Refresh access token
6. Repeat 2-4 3times

Scenario Must start with gradual user increase starting from 10users up to 10K

Tasks:

• create script with required amount of users (will be generated with python automation script)
• create K6S script with upper described test scenario
  • smoke test with small amount of users (~10 users on 1 min)
  • average load (~500 users on 15m)
  • stress test (~10K users on 30m)
• collect all errors and fix the issues
• ensure that p95 < 200ms
