Remote configuration sources #1
Description
now that setting sources are abstracted away with a simple Get(key) interface we can add other remote config sources like AWS appconfig and Azure App Configuration.
another nice feature would be to add Stop, Restart to driver interface to allow for gracefull shutdown/restart and Hangup signal handling. furthermore configurations can implement a watching/pulling based reactor to update themselves and when updated restart the application from ground up.
I am excited for this project and willing to open a PR on any of these features I mentioned above.
