Streamlining exit on error procedures

[fouriaux]

create_report_configuration can fail and raise error using abort(), this lead to an error not necessary easy to interpret from a normal user without a debugger.

this abort and potentially other ones must be replaced by proper error management.

Hi @fouriaux, if you have branch let me know otherwise I will PR.

@tapaswenipathak : I dont think we started anything on this. But I would keep this in queue for time being as we are going to change overall execution workflow soon.

Hi @pramodk, can I work on this or is this internal? I can create a draft PR for proper error management?

[pramodk]

@tapaswenipathak : Sure. We should consider parallel aspects while error handling (i.e. MPI executions). I haven't thought about this in detail but if you already thinking about this / some abstraction, let me know how.

@pramodk Can I go ahead and implement https://github.com/gabime/spdlog? Do you have any package in mind which would work w/ MPI executions?
