- add new metric: `haproxy_backend_agg_server_check_status`
it counts the number of servers matching a specific check status
this permits to exclude per server check status as the usage is often
to rely on the total. Indeed in large setup having thousands of
servers per backend the memory impact is not neglible to store the per
server metric.
- realign promex_str_metrics array
quite simple implementation - we could improve it later by adding an
internal state to the prometheus exporter, thus to avoid counting at
every dump.
this patch is an attempt to close github issue #1312. It may bebackported
to 2.4 if requested.

This change is required to support TCP/HTTP rules in defaults sections. The
'disabled' bitfield in the proxy structure, used to know if a proxy is
disabled or stopped, is replaced a generic bitfield named 'flags'.
PR_DISABLED and PR_STOPPED flags are renamed to PR_FL_DISABLED and
PR_FL_STOPPED respectively. In addition, everywhere there is a test to know
if a proxy is disabled or stopped, there is now a bitwise AND operation on
PR_FL_DISABLED and/or PR_FL_STOPPED flags.
Currently the stats filling function knows nothing about the caller's
needs, so let's pass the STAT_* flags so that it can adapt to the
requester's constraints.
Let's start to better organize the addons by moving promex there (and
with an easier directory name). The makefile and maintainers files were
updated, as well as the CI's build matrix.
