Add config reload on client in case database/connections configuration changes on the server

[dchoi-viant]

From TODO.md.

Currently, the client logic will read the configuration as part of an initiation phase - this then relies on the state of the configuration even if the server restarts or changes any of the relevant configurations, those changes will not be picked up.

Maybe use a block-chain like hashing system for components and dependencies.
