Introduced local profile

@arey please review

When I add below VM options to my ConfigServerApplication, the config server is using my local git repo:

-Dspring.profiles.active=local -DGIT_REPO=/Users/arey/Dev/spring-petclinic-microservices-config

It's perfect. Maybe just add this option into the README?

I've got a question: is it a way to switch between local and github configuration without to restart the config server? I mean, does a micro-service could choose the config it wants to use (local or github) by activating a Spring profile at startup?

I think this is impossible to achieve using profiles which are activated on application startup. Profiles switching would require Spring context to be rebuilt. On the other hand, I think that dynamic repo configuration would be a helpful feature and it might be done using Spring Cloud Bus and @RefreshScope (pushing confit changes to clients) - some research needed.
