d03e48eb75 scx_layered: Implement per-stats-client nr_layer_cpus_ranges tracking 
With this, every client sees the correct nr_layer_cpus_ranges without
interfering with each other.

448aacfd60 scx_layered: Initialize Stats.prev_layer_cycles properly on new() 
So that new stats session doesn't start with an inflated utilization number.

6cba8d786a scx_stats: server: open_ops must be kept throughout a client session 
open_ops tracks which ops have been opened by the client session; however,
it was being created on each handle_request() making every request to open
each time. Fix it by moving it to the caller.

25d7e6f787 scx_layered: Implement on-demand statistics generation 
Instead of keeping one copy of sched_stats, each stats server session
carries their own so that stats can be generated independently by each
client at any interval. CPU allocation min/max tracking is broken for now.

a77fe372d6 scx_stats: Make server shutdown when connection is dropped and add communication channel 
This will make implementing connection sessions easier where each stats
client connection maintains a set of states.

3a688cfde7 scx_stats: Add support for no-value user attributes and a bunch of other changes 
- Allow no-value user attributes which are automatically assigned "true"
  when specified.

- Make "top" attribute string "true" instead of bool true for consistency.
  Testing for existence is always enough for value-less attributes.

- Don't drop leading "_" from user attribute names when storing in dicts.
  Dropping makes things more confusing.

- Add "_om_skip" to scx_layered fields which don't jive well with OM.
  scxstats_to_openmetrics.py is updated accordignly and no longer generates
  warnings on those fields.

- Examples and README updated accordingly.

870a262713 scx_stats: Add scripts/scxstats_to_openmetrics.py 
This is a generic tool to pipe from scx_stats to OpenMetrics. This is a
barebone implmentation and the current output may not match what scx_layered
was outputting before. Will be updated later.

INSTALL: Update Fedora installation docs 
The guide that is currently available for Fedora sched-ext is outdated. To remedy this,
I have opted to update the guide to use CachyOS's kernel that is also available on Fedora.
The scx schedulers that are available on Fedora's repositories are also outdated and doesn't work
with the current patchset. I have also updated the scheduler installation to use our package
in the CachyOS Addons COPR.
