refactor: migrate the ego-server code from different repo to dcr

[qascade]

Description

Currently the server code is on a different repo and is deployed separately. I want both the repos to be merged and a flag to be added on the dcr run cmd to specify that we want to run on server mode or local mode. The server code is to be refactored to make it maintainable as well as idiomatic.

Server Code: https://github.com/tiklup11/dcr_ego_server

You can run the server using go run main.go in the server repo. Then change the url inside service/client.go to https://localhost:8080. Then the dcr cli can be used as a client
