the class TestAllocators method ensureDrillBufReadIndexIsZero.

 * Contract for DrillBuf[] returned from getBuffers() is that buffers are returned in a reader appropriate state

 * As data being read from DrillBuf, readIndex will be pushed forward. And, later on,
 * when DrillBuf[] are read from the ValueVector, readIndex will point at the location of the most recent reading

 * This unit test is added to ensure that the readIndex points at zero under this scenario
