v1.7.0 Release Candidate 1

First release candidate for CNI v1.7.0. This pre-release image is only available in us-west-2 and there are couple of changes that require some extra attention:

• #972 - We persist internal state of the aws-node pod to a file and use that to recover after a restart. Because of that, just changing the image tag will not work. Please update using the latest config file.
• #955 - Added init container to copy portmap and loopback binaries, and set up rp_filter. This means the aws-node permissions can be reduced from privileged to just "NET-ADMIN"
