Description

First round will just be to expose the ability to set priorities for client operations. For more background: http://mail-archives.apache.org/mod_mbox/hbase-dev/201604.mbox/%3CCA+RK=_BG_o=q8HMptcP2WauAinmEsL+15f3YEJuz=[e-mail]%3E

Next step would be to remove AnnotationReadingPriorityFunction and have the client send priorities explicitly.
