To be consistent with random_distribution add a normal parameter to
file_service_type and state that gauss is an alias of it.

For *random*, *roundrobin*, and *sequential*, a postfix can be appended to
tell fio how many I/Os to issue before switching to a new file. For example,
specifying ``file_service_type=random:8`` would cause fio to issue
