(QENG-1906) Refactor initialize to allow config passing
Prior to this commit, several pieces of vmpooler performed configuration and initialization steps within 'initialize'. This made it difficult to pass in mock objects for testing purposes. This commit performs a single configuration and passes the results to the various pieces of vmpooler.
