Changed Default Log Level to INFO for the Simulation Logging

[DhruvSondhi]

This PR aims to change the default log level to INFO and compare the changes with this setting for the simulation. Implementation for #1839.

Description
The default log level for the simulation logging is CRITICAL at the moment. This PR aims for change that to INFO wrt to Issue #1839. The intended change would show more information when the simulation is running & status of the simulation.

Motivation and context
Intended change for imparting more information to the user when the simulation is running.
But with this change in place, the intended usage of the Convergence Plots and Progress Bars is defeated. As more logs are outputted when the simulation is run, Jupyter notebook tends to scroll downwards and hence plots and progress bars cannot be scene. Also, scrolling when plots and logs are being output, it becomes buggy and slow. For more information check the video attached to compare the difference with this change and the original way of the log settings.
