Singularity runOptions add parameters to avoid loading home directory libraries for R or Python

[gongyixiao]

So far we have been seeing this issue in here: taylor-lab/annotateMaf#5

Without below two new parameters, singularity R session still load plyr 0.8.3, not plyr 1.8.4 which is installed in the container.

runOptions = "-e --no-home -B $TMPDIR"

Need to make sure this runOptions change won't invalid caches in other directory. It doesn't mean it shouldn't, but we have to know exactly what will happen and if that makes sense before we deploy it. We can use -dry-run option in nextflow to check this.
