Update the worker snapshot volume for 2017 CDL

[mmcfarland]

Overview

The CDL tif has been updated to the 2017 version and placed on the snapshot identified by the id added to our packer template.

Connects #407 Connects #377

Demo

I ran a scenario on the 2015 raster and another scenario on the 2017 version. As you can see, one version had Cucurbits dropped between versions.

Notes

The 2017 CDL was reclassified according to the excellent notes in the readme. The articaft, aside from being available on the snapshot volume, is in the publically available icp-cdl-data. As the readme indicates, the 2017 prefixed version can be copied (sans prefix) to your host /opt/icp-crop-data directory in order to use/test it locally. The other proportions remain largely the same.

Testing Instructions

• Update your local CDL version, as described in the Notes above.
• Confirm you can still run the pollination model with reasonable results
• Confirm the snapshot ID is valid.

When this is merged, we can verify that it's being used on staging.

Taking a look now.

This was deployed to staging and you can see in this screenshot that the baseline scenario (taken on the 2015 version) differs from the current (2017) version - tree fruits (other) have been classified out.
