Storage Sampler for macos
Disk metrics for System Sampler

To take into account:

APFS partitions share total bytes and free bytes information
IO counters only for physical drives not partitions

In macos partitions don't have IO Counters related data so samples won't. But we can use Storage Sampler IOCounters for IO related information inside System Sampler. This is the reason of exporting these 👇

This test was failing on macos. Removed from macos tests to move forward while investigating and maybe involving coreint team.

macos-11 giving errors

which ones? I only get to see 10.15 errors on the GHA record

Some "unexpected errors" : actions/runner-images#841
Same screen as in the link :(

I saw in the comments that wasn't happening in 10 and didn't have any since I changed it

Those are being read from the host machine, and so they have different values depending on where are being run. As I enabled tests in this PR they are raising now :(
I will improve the comment above 😅

//Commented until fix these test (out of scope in this task)

edit: now I realised that it's not properly fixed, as I assert against expected :carlton: . Updating comment and fix
