Reloadable plugins eventually causes ATS to crash on config reload

[mtorluemke]

After running ATS9 for ~45 days (reloading configs once/day), crashes are seen when configs are reloaded with a message like:

traffic_manager[<<PID>>]: warning: Could not load shared library symbols for 8 libraries, e.g. /var/run/trafficserver/<<UUID>>/<<ATS installed directory>>/plugins/conf_remap.so.

And, the stack trace is always:

Wasn't not the case? Not a time-based issue, rather a double-delete issue: #7862

If this is still an issue please reopen. @vmamidi Says this was fixed by #7862.
