DESIGN: Ensure we can make arbitrary config updates in TDX deployments.

[netrome]

Background

Currently, our TDX deployments assume we pass environment variables to the node docker image which is used by the node start script to generate a configuration file once. There is no way to update this configuration on a running deployment or to pass custom configuration to the nodes.

This is especially problematic since we implemented foreign transaction validation, as we do expect frequent configuration updates to add support for more chains and RPC providers.

User Story

As a node operator I'd like to be able to update our configuration.

Acceptance Criteria

We have designed a solution for how to be able to dynamically update configuration files of our deployments.

Resources & Additional Notes

For foreign tx validation we also want the ability to add new environment variables with API keys, or support another way of confidentially forwarding these to the nodes.

Spitballing, I'm thinking if we just want to expose some kind of admin UI for this where the config can be read and modified. We probably want to support other node actions as well such as restarting nodes etc.

We've agreed on the design and @DSharifi has already started incorporating it in the Rust launcher
