nit: Maybe the name can be EnvManager to reduce its length

This value is currently hardcoded, and I think we need a more robust approach to configuration management. Otherwise, the number of command-line flags will quickly become unmanageable and difficult to maintain.

This PR introduces an in-memory cache to store parameters that rarely change, reducing the number of requests to the backend database. However, it should only be used for bounded values—such as the environment and node key—because the cache is currently unbounded and may grow indefinitely, potentially leading to OOMKilled errors.
At this point, the cache has been added for the
environmentvalue only.
