Is your feature request related to a problem? Please describe.

There are a number of metrics available that are useful (and that may already be collected from the API as far as I can tell), but not currently being made into metrics. Adding these metrics would help to have parity with the monitoring graphs that MongoDB Atlas has to offer natively.

The list is:

• mongodbatlas.process.cache.ratio
• mongodbatlas.disk.partition.throughput
• mongodbatlas.disk.partition.queue.depth

Describe the solution you'd like

1. Add new metrics:

mongodbatlas.process.cache.ratio to be placed under a Process resource.

mongodbatlas.disk.partition.throughput
mongodbatlas.disk.partition.queue.depth to be placed under a Process/Disk resource.

Describe alternatives you've considered

Seems like a good addition! Do you have specific API docs you can link on how you're going to source these metrics/if they require extended permissions?

@schmikei We actually are already retrieving all of the data for these metrics already. No additional API calls would be necessary.
