Merge `hybrid_performance` into `hybrid_ya_perf` checker and deploy it

[wkargul]

We faced a few issues when runnin hybrid_performance checker. Those issues are listed below.

Issues with hybrid_performance checker:

• checker does not run according to the schedule,
• no results in /tmp/test_result_hybrid_performance,
• requestor does not pay for running task

as this is overhead to maintain two checkers we decided to merge 'hybrid_performanceintohybrid_ya_perf` checker

As discussed (What should be done):

• merge hybrid_performance into hybrid_ya_perf checker
• add comments to run.sh scripts in ya_perf checker to highlight why particular part of the sccript is triggered ➔ ya-perf checker for performance measurements, performance checker for stress tests
• scope of the scripts:
  • ya_perf part of the script:
    • 10 various nodes, transfer file for GFTP equal to 50MB, 10 pings:
      • GFTP transfer test
      • VPN ping
      • VPN transfer test using iperf3 (which ya_perf tool use by default)
    • 10 fixed nodes, transfer file for GFTP equal to 50MB, 10 pings:
      • GFTP transfer test
      • VPN ping
      • VPN transfer test using iperf3 (which ya_perf tool use by default)
  • performance part of the script:
    • 50 various nodes:
      • VPN transfer test using scp with 10MB transfer file size (setup ya_perf tool accordingly)
• inform Devops about significant increase of tasks run time (as alerts may appear too often if Grafana is not adjusted respectively)
• when merge is done, deploy changed checker and observe for possible issues
