Need of a settings management system

[TanmayArya-1p]

A user should be able to edit and change settings for the application which can be used for various needs.
For instance to solve #10 (Password Generation) it would be messy to save configuration options like Password length,etc in a separate config file.
Instead of each contributor using a different config file for their implementation there can be 1 provider that stores all configuration options.
There is a need for an api that people can query to fetch configuration options for their feature
