feat(agent)!: add support for mTLS authentication in gRPC server (#54)

Browse Source 
* refactor(fancontroller): improve fan controller validation logic and error handling for temperature steps

* refactor(agent): restructure gRPC server implementation by moving it to a new api package for better organization and maintainability

* feat(agent): implement gRPC server for managing compute blade agents and add graceful shutdown support
refactor(agent): restructure agent code by moving API logic to a dedicated file and improving error handling
fix(agent): update logging messages for clarity and consistency across the agent's operations
chore(agent): remove unused API code and consolidate event handling logic for better maintainability
style(agent): improve code formatting and organization for better readability and adherence to conventions

* feat(agent): add support for TLS configuration in gRPC server

* feat(api): add gRPC server authentication

* fix

* feat(config): add listen mode configuration to support tcp or unix sockets
feat(agent): implement listen mode in gRPC service to allow flexible socket types
feat(bladectl): enhance configuration loading and add support for TLS credentials
fix(bladectl): improve error handling for gRPC connection and event emission
style(logging): change log level from Warn to Info for better clarity in logs

* add logging middleware + fixes

* fix remote-connection to gRPC API Server

debugging the SAN issues took the soul out of me... And then the stupid
mistake in cmd_root where I didn't construct the TLS credentials
correctly... Oh dear...

* cleanup

* cleanup

* cleanup commands

* move bladectl config into correct directory

* fix bugs

* // FIXME: No dead code

* nit: code style

* nit(YAGNI): you aint gonna need it. Don't make life harder than it needs to be

* nit(YAGNI): you aint gonna need it. Don't make life harder than it needs to be
