Cosmetic changes
@mariogiov I do not agree with this implementation... why the part that implements the engine utilities needs to connect to charon. Moreover to retry en information that was already available in the conductor.
I agree with passing a sample_obj to piper_ngi (I was passing a charon sample entry) but as you add to the object the status you need to add also the number of reads and the total autosomal coverage so that piper_ngi has all the info to process the sample in an agnostic way (i.e., it does not matter which DB are we using, piper_ngi receives a sample_obj with well known fields)
