* Enforce not using Maven 3.6.2

* Use Maven 3.6.3 via Maven wrapper for Travis

Previously, if you defined maxexecutiontime and not defined operationcount
parameter (or set operationcount=0), then you were able to run YCSB for a
given period of time and measure the number of operations you get during
the load test.

Since #1323 was merged, it it not possible to use operationcount=0, as
the thread count will be set to 0 in this case and no client thread will
be created. This PR makes it possible to use operationcount=0 again.

Method nextBuf is a clever hack that outperforms Random.nextBytes
but performs poorly for all other ByteIterator implementations

This commit moves it to RandomByteIterator and adds efficient
toArray implementations for other ByteIterator classes.

Also InputStreamByteIterator.reset method that unconditionally
throws UnsupportedOperationException is fixed
