Run all EnvironmentPostProcessors on refresh. (#969)

Browse Source 
This includes ConfigDataEnvironmentPostProcessors which replaces the static call.

Issue #968 was specifically about the cloud foundry vcap post processor. Previously the DecryptEnvironmentPostProcessor was hard coded in ConfigDataContextRefresher

Fixes gh-968
