Description Bernard Cafarelli 2023-01-16 10:50:05 UTC 
This bugzilla goal is to complete upstream launchpad bug [0] and include it in OSP:

At the moment, there is no limit on how many requests the metadata-agent will handle. Some users may sometimes run scripts in their instances that
try to query the metadata endpoint at high rate (for example a bugged k8s cloud controller manager), causing an increased load on some or all the
component above the metadata-agent.

Spec was accepted and merged [1], but proposed code change was not fully completed [2]
