Create an Installation script to automatically install and setup the project

**Is your feature request related to a problem? Please describe.**
Currently the installation and setup of Mentorship Backend is done manually. It would be great to have a single script which could download the code and setup the various configurations required automatically.

**Describe the solution you'd like**
Create a shell script named **install.sh** (for Linux/Mac) or **install.bat** (for Windows) which would do the following when run -
- Clone the repository to the present working directory of the running script (if not already inside one, which will mostly be the case )
- Perform all the required setup for the repository to run. Take any variable inputs as mandatory command line arguments, without which the script will produce an error, and prompt the user to enter the values.
- Perform unit testing on the installation and display its results

**Describe alternatives you've considered**
To modify the deploy.sh file to work on local systems
