Modify genotype filtering to ingest cutoffs from a table

[kjaisingh]

Description

This PR is intended to enable the use of a generalizable TSV file that contains cutoffs stratified by SV type, minimum size and maximum size when filtering genotypes.

In doing so, it also separates FilterGenotypes into two distinct workflows - a TrainGenotypeFilteringModel workflow which trains the machine learning model, and a FilterGenotypes workflow which applies the filtering using the trained model and input cutoffs.

Testing

• The following job represents a run of the original WDL.
• The following workspace contains a run of the modified pair of WDLs with the original cutoffs from the job above passed, albeit in the form of a table rather than named arguments. As you can see, the output filtered_vcf in the latter workflow is identical to that of the above workflow.
• Validated all WDLs with womtool.

Pre-Merge Changes Required

• Add template SL cutoff file reference to GATK-SV resources bucket.
• Remove automated sync of WDL to Dockstore.
