BCL API Review: Move ConfigurationBinder functionality into its own package in the Configuration repo

[divega]

#205 moved the POCO binding functionality from Options directly into the ConfigurationModel package. In order to align Configuration with BCL requirements across different platforms we want to keep the core configuration package free of hard dependencies with reflection.

This also aligns with the decision that at the core, Configuration is only going to deal with strings, which is reflected in #199.
