[STORM-1505] Add map and flatMap functions in trident stream
map and flatmap are common stream operations. Right now in trident this has
to be
implemented via each() which also sends the input field values
in addition to the mapped field values, so the map and flatmap should make
things slightly
more efficient and easy.

Added filter api
filter is a wrapper over each to easily filter out tuples flowing through
the pipeline.
