Capability to run from Config file

[LeoBorai]

It would be nice to have a HttpServer.toml we could use to spin up server.

When running the server as:

http-server --config ./HttpServer.toml

The Configuration would be read on init to build server with desired configuration.

1. Abstract Cli into a Config struct
2. Provide an initialization process to read HttpServer.toml and build a Config from it
3. Build server with such implementation
