acl-plugin: an elog-based tracing implementation for troubleshooting the conn cleaner threads interactions
This replaces some of the early-stage commented-out printf()s with
an elog-based debug collector.
It is aimed to be "better than nothing" initial implementation to be available
in the field. It will be refined/updated based on use. This initial code
is focused on the main/worker threads interactions, hence uses just
the worker tracks.
This code adds a developer debug CLI "set acl-plugin session table event-trace 1",
which allows to gather the events pertaining to connection cleaning.
The CLI is deliberately not part of the online help, as the express
declaration that the semantics/trace levels, etc. are subject to change
without notice.
