run nf-test with awsbatch executor

[fmalmeida]

Hy dev team, Thanks for this nice tool.

When trying to execute nf-test with awsbatch it failes with:

Nextflow stderr:
  
  When using `awsbatch` executor an S3 bucket must be provided as working directory using either the `-bucket-dir` or `-work-dir` command line option

even tough workDir is set to a S3 path in nf-test.config.

I saw that the S3 path actually was created locally by nf-test. So my question are:

• Is this a known limitation by design? If so, there are plans for integration?
• Or else, is there something wrong that nees fine-tuning?
