Port Fix for "MariaDB Connector Time Out Issue" to 2.2.x (already prepared, need project allocation to fork and request merge)
Recently, a fix regarding database timeout handing (reported in #2688 (closed)) was merged into master (!1887 (merged)). Since this problem is also present in the v2_2
branch, I have cherry-picked the commits of the MR and applied them on the stable version.
Since I cannot open a Merge Request on ISC's Gitlab I submitted these to https://github.com/isc-projects/kea/pull/125; but @vicky advised me to open this issue to get a project space allocated here. For now, my patches live at https://github.com/uedvt359/kea/tree/dvt.
