@sazzad16 it is really hard to see what is #2078 is adding on top of #1968

1. Almost all of Jedis methods that takes a count param, receives it as an int. There are only two exceptions in Jedis class. As zpopmin is yet to release, I changed its count to int.

2. ZPOPMIN without count returns only one Tuple (or none). Instead of returning a Set<Tuple> with only one element, it'd be better to return Tuple. ZPOPMAX implemented zpopmax, zpopmax with count #1968 is changed to be like that. I included this change in this PR.

@gkorland I forgot that I had changed the same changes added most of the changes of this PR also in 915a810 which are merged through #1968 just now. As a result, there are not much left to see separately.
