This adds a new gearman worker to process the subunit files from the gate job runs. It will use subunit2sql to connect to a sql server and process the data from the subunit file. The log-gearman-client is modified to allow for pushing subunit jobs to gearman, and the worker model for processsing logs is borrowed to process the subunit files.
