DOCS ☂️ Rework high-impact tutorials

[philrenaud]

Recently, we've taken a look at some of our tutorials feedback for Nomad and noticed some outliers in terms of helpfulness responses and feedback.

The following tutorials are good candidates for updates or rewrites:

• [ ] Deploy and Manage Applications
  • currently serves as a book-jacket more than a guide. Candidate for removal in favour of other tutorials?
• [ ] Set up a Nomad Cluster on AWS
  • "It would be a nice-to-have if this tutorial had a version that only dealt with Nomad."
  • some code outdated (TF should switch to Templatefile use; etc.)
  • server nodes fail on health check / consul errors on startup
  • "Inconsistent dependency lock file" error
  • Destroying and restarting cluster causes errors
  • ami needs to be updated
• [ ] Set up a Nomad Cluster on Azure
  • Outdated; does not work for Ubuntu versions higher than 16.04
• [ ] Deploy and Update a Job
  • noted redis ConnectionError from the web app on :5000. Possibly mac specific?
  • "had trouble following along" / "a single docker workflow deployment would be better"
  • [ ] Create a Cluster
  • A lot of the comments indicate "This is just setting it up locally / not a real-world scenario", so maybe the solution here is to have an introduction "choose your own adventure" of "Do you want to create a cluster on your local machine? or on $cloudProvider?"
• [ ] Enable Gossip Encryption for Nomad
  • nomad operator keygen deprecated, should use `nomad operator gossip keyring generate]
• [ ] Introduction to Nomad Pack
  • Include make, go, and hclfmt under requirements/deps (and installation instructions?)
  • "The github URL is incorrect. It's missing the ".git" at the end."

I moved the corresponding Jira task to the Runtime Education project and let Jeff know.
