Sample-level pbsv run doesn't compress and index the output VCF

[vsmalladi]

In pbsv.wdl file, we call: bcftools_concat_pbsv_vcf. Then we need to bgzip and tabix the output_vcf, something like this is needed:

call common.bgzip_vcf as bcftools_concat_pbsv_vcf_bgzip { input : vcf_input = bcftools_concat_pbsv_vcf.pbsv_vcf pb_conda_image = pb_conda_image }
