The docs for this command were woefully out of date. This change clarifies the wording since we're really upgrading the schema in the database, not "synchronizing" it even though that's the name of the command - the migration scripts run the 'upgrade' method only. Also, it was saying this was how you created the main database, which is totally wrong since this command doesn't create the database. The deployer creates the database, this command migrates the schema on that database. Then I also added the arguments along with a description of each and noted that this will by default upgrade the cell0 schema. Change-Id: I3d40cb32c325bc3f665e727b921082efba043192
