[dex] Add inspec tests and update documentation

[gavindidrichsen]

Since dex is a habitat service, then in azuredevops it should be built, exported, and tested in docker. Summary of features here:

• inspec tests added
• documention updated
• issue [dex] hab service runs but returns 404 error #1 raised because although the dex habitat service runs successfully, the http endpoint appears to be broken

All inspec tests are passing in local docker export:

hab pkg exec chef/inspec inspec exec /src/dex/. --chef-license=accept -t docker://core_dex --input-file /src/dex/attributes.yml.studio.yml
