[EPIC] Add persistence for the editing done by the user

[puchka]

Store the edit made by a user in a database

• bus line {id, name}
• list of bus stops {id, name, location, order}

EDIT: This should probably be done in https://github.com/BetaX-Community/map-data-server or in the mono repo if we merge the two of them.

We could use the same persistent layer as in this repo: https://github.com/srishtiprasadmanit12/Job-Tracking-Application

It also gives an example of a mono repo for integrating both map-data-server and editor together.

Any thoughts here?
