dynamically set computational resources request based on how many lanes are in cidr samplesheet

[Kurt-Hetrick]

current pipeline submits to the c6420 series and takes up the whole node. when the requirement for an iem sample sheet has been removed, i think that you can submit multiple flowcells. however, since there are only 8 nodes, this can create a backlog. it might be better to lower the number of threads used and java max heap space and use up more nodes when there are more than 8 lanes in a sample sheet.
