Allows for a RestBasedBackend class that could leverage a backend coded through a rest API

[BDonnot]

Is your feature request related to a problem? Please describe.

There is no direct problem linked to it.

It would be nice however to be able to use some other libraries to serve as backend, possibly coded in other langages (for example powermodels coded in julia, matpower in matlab etc.)

Describe the solution you'd like

This class would allow, once a server started, to communicate using rest API calls to a powergrid simulator. Said simulator would perform the computation and then return the result.

Describe alternatives you've considered

There's no real alternative beside:

• developping this kind of API for all application we want to connect (slow and work would be done multiple time)
• recoding the solver that we want to use as backend in a "python compatible" language (eg python, c or c++)
