The feature was listed as experimental on the docs page describing this
feature, so we're free to change the key to match the worker name.

The frequency was improved too, so the peaks would be lower, and
accuracy would be better. The default cron pattern was choosen so it
would spread the load between other scheduled jobs nicely.

Allow setting `usage_ping_enabled` in `gitlab.rb`

See merge request !1543

This setting is passed through to the Rails app, and defaults to true. Setting
it to false:

1. Disables the usage ping.
2. Prevents the usage ping from being enabled through the admin panel. It can
   only be enabled by either removing the line from `gitlab.rb` and configuring
   through the admin panel, or setting it to true in `gitlab.rb`.

Use a YAML generator instead of a hand-crafted Chef template.
* Avoids invalid YAML syntax.
* Allows exporter recipes to self-register their scrape configs.
* Allows for easier extensions to the existing configs.
* Minor hack to avoid Chef's attribute magic[0].
