 Description   

On crashes/segfault we have a “semi-automated response” that we should have a repro in order to investigate and resolve an issues, which indicated that our logs only have part of the information.

I think we should improve our debugging ability by leverage core dumps, this will give us the full context for an offline debugger and should help us to resolve many stress w/ the first iteration.

Add the ability to provide core dumps on fassert and invariant failures

I'm going to rephrase this ticket to emphasis the addition of core dump to asserts, since we already have the ability to produce core dumps. per SERVER-12259
