RFR: 8313083: Print 'rss' and 'cache' as part of the container information [v2]

[Gerard Ziemski]

> We add "rss" and "cache" metrics to cgroups v1 and v2
> 
> For cgroups v1, those metrics are named accordingly and are retrieved using the same names.
> 
> For cgroups v2, those metrics seem not to be directly provided, but instead we need:
> - `"anon"` for "rss"
> - `"file"` for "cache"
> 
> The cgroups v2 docs do not actually state this equivalence (https://docs.kernel.org/admin-guide/cgroup-v2.html), but instead this comes from reading cAdvisor src code - https://github.com/google/cadvisor/blob/2129e1c4fae8567551d1ac252c7a1dec27617e21/container/libcontainer/handler.go#L814C4-L814C4
