v1.6.4 Release Candidate 1

First release candidate for CNI v1.6.4. This pre-release image is only available in us-west-2.
The main reason for this patch release to address issue #711 by cherry picking the fix in PR #972 to the 1.6 branch.

Bug - Use docker/CRI to discover pods at node init(#1118 , @fawadkhaliq / @anguslees )
