I'd like to see SimpleMDM report on installed certificates for all device types. A common feature in other MDMs, CertificateListCommand (https://developer.apple.com/documentation/devicemanagement/certificatelistcommand) has been around since iOS 4 and macOS 10.7 (!).

While we have other tools to report on certificates (like osquery), it's useful to have MDM as a data source as well since oftentimes installed certificates originate via profiles. Knowing certificate health within the same product has benefits, and could allow for more advanced certificate management directly in SimpleMDM.

Important fields...
- Certificate name
- CA/issued by
- Expiration
- Current validity status
- If possible, whether the certificate is "managed" (installed) by a MDM profile.

And, of course, please make sure certificate data is available via the API, preferably using the existing devices endpoint.
