70ba4cb9ef scx_stats: Fix multiple labels handling in scxstats_to_openmetrics.py 
OM labels() was called with an array which is then incorrectly interpreted
as a single label. Unpack it to list of arguments. While at it, make error
reporting a bit more robust.

4e859d067e scx_stats/scripts/scxstats_to_openmetrics: Retry connection 
It now retries until told to exit. This is a bit easier to use and matches
`scx_layered --monitor`.

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.

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.

689d380db1 scx_stats: Implement ScxStatsServer::add_stats_ops()

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.

that there can be multiple comma separated attributes in a single block.

- s/stat/stats/ on several stragglers.

Use plural form which is more widespread and also used in scheduler
implementations. No functional changes.
