This updates the ISA-L compression driver guide on how to enable and use
checksums.

This also updates the compression drivers features matrix.

V2:
Documentation Changes
V3:
Added Release note

Hi Lee,

A humble suggestion being shared for document update, Based on DPDK 19.02-rc1 release both code and associated document update is to be in single patch file.

Note: I am not fully sure how this is applicable to 'isal.ini and isal.rst'. It will be good to have a check.

Thanks
Vipin Varghese
