Feature Request: Container disk storage usage observability

[ss-proc]

Is your feature request related to a problem? Please describe.
Azure Container Apps should expose disk usage. We have a .NET background image processing service that creates a lot of temporary files (which gets cleaned-up by another garbage collector) but it is important for us to monitor that we are accidentally hitting the container storage limits. The observability guide https://docs.microsoft.com/en-us/azure/container-apps/observability?tabs=bash#azure-monitor-metrics does not expose the disk space used. I understand that disk space is shared among all running containers but every container must have an upper limit.

Describe the solution you'd like.
A new metric in Azure Monitor that shows available storage vs used storage space.

Describe alternatives you've considered.
Create a prometheus scrapper but it very cumbersome to maintain it.

Additional context.
Background services that generate media will face this issue.
