hook for saving coredumps and generating stacktraces out of them

<mmrazik> it should be possible to archive core dumps as test artifacts
<mmrazik> it probably would be possible to generate stackreates out of them (statically)
<mmrazik> but dynamically attaching gdb and doing something would be tricky
<tbf|afk> mmrazik, gdb backtrace as in "threads apply backtrace full" (or what the command was) would be awesome
<tbf|afk> mmrazik, in most cases much more useful than downloading the cores, getting the proper binaries and fiddling with gdb yourself
