[SPARK-20114][ML] spark.ml parity for sequential pattern mining - PrefixSpan
## What changes were proposed in this pull request?
PrefixSpan API for spark.ml.
Note: Currently there's no sequential rule mining support in
`mllib.PrefixSpan` so we cannot implement `PrefixSpanModel.transform`. In this
PR, the transform do nothing. Or we can throw out unsupport-operation
exception. I am open to both of them.
## How was this patch tested?
Testsuite added.
