COR-772: Update Cortex ES to 5.x

[ElliottAYoung]

Purpose:

See #416

This sets the stage and makes the necessary changes to update Cortex's elastic search from 2.4.1 to 5.4.0. Changes in this PR include:

• Bump Cortex Plugin to new version for Beta Cortex ES compatibility
• Update publish_filter ES query to work with 5.4.0 syntax
• Remove pesky deprecation warnings

Before we start building our wonderful mappings, queries, filters and sorts for Beta Cortex, we need to upgrade ElasticSearch from 2.x to 5.x, so that we don't have to reinvent these queries in 6 months when we're forced to upgrade for some feature we need.

Server is down, redeploying

@ElliottAYoung @toastercup does this need a push to at least stage before we can review (like testing endpoints and pages)? if so I'll hold off

[ElliottAYoung]

@arelia no - this can be tested in any environment
I technically have a server up with these changes live at http://web.cortex-6.development.c66.me

[arelia]

@ElliottAYoung ok, I was thinking we needed to test pages and endpoints with more content.

I'm testing on your dev env and I don't see all 4 posts here: http://web.cortex-6.development.c66.me/api/v1/posts/feed?per_page=100

I'm expecting cache needs to clear and I have to wait for it. Will try in the morning

@arelia make sure those posts are published, the feed endpoint only shows posts that have a published date in the past
