Pull Request Template

Description

A new endpoint is created called /gcbm/status. This endpoint will return the status of the running GCBM simulation and the logs generated in simulation.txt. This endpoint will be called by the FLINT-UI to get the latest status of the GCBM simulation. In this manner, the user will be able to check if everything is working correctly or if there is any error. If the simulation is not running a 400 status will be returned to the user.

Fixes #179

The test case is failing for some other endpoint of GCBM simulation. Earlier I added some test cases for this endpoint they were not working as expected so I had to remove them. I am working on adding some new test cases for this endpoint.
