* Updates to config handling - Add functions to load in configs - Standardize location and naming of config files - Configuration over convention style of config file handling for each service * update config handling and correclty handle cli flags being set * generate configs from default if no config is found - renamed pointerdbDB to pointerdb for clarity in config file - set sane default for pkg/overlay boltDB file - set srvPort to default to 8082 to avoid port collision on default setting * linter updates * move boltdb path vars into function * update tests to handle config environment changes * --fix exec test mocks * update tests to use viper instead of flag library * fix typo * add redis-server to services in travis for tests * update examples with new config env function signature * fix tests
