Updated handling of appendables in MRTask2. Appendable Vecs are kept separate from normal Vecs so they can be passed directly instead of via K/V stored and roolups can be computed in standard M/R way.

Vector separation is kept also in map calls, which now have inputs (Chunks) and outputs(NewChunks) separated.
Also, users do not directly create Appendable Vecs, they simply tell MRTask how many output vectros they want to create.

Replace BASHPID with $$.
GLMGrid does not support destination_key parameter.

Only GLM page supports destination_key parameter but not GLMGrid.
The parameter 'parallel' is not supported by GLM only by GLMGrid.
Type in python parameter pollTimeoutSecs.

Some tests were referencing parameter pollTimeoutsecs which is
not declared by Python API. They should reference pollTimeoutSecs.
Passing GLM/RF parameters to Parse does not make sense.

Test created **kwargs for GLM/RF and passed them to parse.
