Enhance "Get Help" page

[jst-cyr]

URL: https://developers.sitecore.com/help
Lower priority request for enhancement on the "Help" page. Currently, this only has a single link to Support, a few recent Stack Exchange questions, and is really hidden in the footer.

Users coming to the developer portal are trying to solve a problem and we should position this page more prominently. Can we make this a larger, more prominent, visual in the footer so that folks know to go here to get help?

For the page itself, we should highlight different ways of getting help:

1. Support (as today)
2. Services and 360 (from Sitecore)
3. Partners (for customers)
4. Sitecore Stack Exchange (for community questions/support)
5. Slack (for community discussions on complex topics)

We may be able to steal some of this from the Community page that highlights the community channels
