Implement Logging Level Support for Tratteria Components

[kchiranjewee63]

Current Behavior

Currently, the log level for all Tratteria components (tconfigd, Tratteria Service, Tratteria Agent) is set to 'info' by default. There is no documented support for changing logging levels, limiting the ability to troubleshoot and debug effectively.

Desired Behavior

Implement proper logging level support (debug, info, warn, error) for all Tratteria components, with the ability to update levels dynamically where possible.

One Potential Solution

1. For Data Plane (Tratteria Agents and Tratteria Service):
   • Use TratteriaConfig (namespace-scoped) to supply and dynamically update log levels.
   • Allow overriding the global log level set by TratteriaConfig:
     • For Tratteria Service: via environment variables
     • For Tratteria Agents: via annotations in service deployments
2. For Tconfigd:
   • Read the log level from its static configuration file.

Questions for Discussion

• Do we need to support dynamic log level update for tconfigd? If so, what would be a good approach to achieve it?
