Support for selective synchronization as a startup flag

[jmordica]

Details

This handy feature allows for specifying a startup flag -syncType ONE | ASYNC | QUORUM When no -syncType specified, it defaults to QUORUM. This is handy for people using MySQL clients and for anyone that doesn't want to have to specify on every INSERT/UPDATE/DELETE.
