Removed old storage
Simplified Dependency injecion
Fixed indentation and spaces

I was not sure what style are you following so I made changes
to follow Laravel style. If braces on empty lines. No spaces spaces
on the end or start of arguments
fixed provides array
Refactored configs management

I simplified the config settings and made it more DRY
Also I renamed the setConfig method to loadConfig as the
name was confusing with actually setting (changing) settings
I also removed all occurence of " for consistency
Basic blank implementaion of interface
Imlemented storage methods
