* Add top level tests * Add a skeleton for preparing buffers * Initialize graphite instance * Prepare buffers for all instances * Add Grafite collected value formatter * Add support for exporting.conf read and parsing * - Use new exporting_config instead of netdata_config * Implement Grafite worker * Disable exporting engine compilation if libuv is not available * Add mutex locks - Configure connectors as connector_<type> in sections of exporting.conf - Change exporting_select_type to check for connector_ fields * - Override exporting_config structure if there no exporting.conf so that look ups don't fail and we maintain backwards compatibility * Separate fixtures in unit tests * Test exporting_discard_responce * Test response receiving * Test buffer sending * Test simple connector worker - Instance section has the format connector:instance_name e.g graphite:my_graphite_instance - Connectors with : in their name e.g graphite:plaintext are reserved So graphite:plaintext is not accepted because it would activate an instance with name "plaintext" It should be graphite:plaintext:instance_name * - Enable the add_connector_instance to cleanup the internal structure by passing NULL,not NULL arguments * Implement configurable update interval - Add additional check to verify instance uniqueness across connectors * Add host and chart filters * Add the value calculation over a database series * Add the calculated over stored data graphite connector * Add tests for graphite connector * Add JSON connector * Add tests for JSON formatting functions * Add OpenTSDB connector * Add tests for the OpenTSDB connector * Add temporaty notes to the documentation
