Description

Reverts a part of the changes from https://github.com/apache/arrow/pull/1479 concerning the plasma::Create API. It should output a shared pointer to a Buffer instead of a shared pointer to a MutableBuffer. This is needed for https://github.com/apache/arrow/pull/1445 so we can return a CudaBuffer from plasma::Create. It also seems to be more in line with how Buffers are intended to be used and avoids API breakage from 0.8.0 to 0.9.0.
