added intial error report before config load of dist-datastore config is verified as valid
removed commented out code
added initial error report to health check service for metrics service. this will report errors for metrics service configuration until verified that configuration is valid
added check of file existence for metrics service config. since the metrics service config is optional the initial health report of error was not being resolved. this update checks if the metrics config was not present (default config is applied) to resolve the health check report
added file existence check for dist datastore service to clear health check report
added initial health check report error when http connection pool service is initialized. This error will be cleared once the configuration is read and loaded
modified good dd config to include required port configurations
updated config loading/reloading tests to pass dist datastore port to parameters
added notes on logic for reporting to health check service
