FASTQ integrity check to be added to new-service tool

[juanledesma78]

Before starting the data analysis of a service, it would be worth checking the integrity of the FASTQ files in case any file is corrupted. At the time being, this check can be manually done by using

md5sum -c md5sum_Instrument_GEN_XXX_YYYMMDD_User.md5

being the .md5 file located within the directory where the FASTQ files have been trasferred.
Adding this check would avoid unnecessary delays for the service.
