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.

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`.

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.

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.

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.
