Fix port issue to use METviewer GUI with Singularity on AWS

[fossell]

Currently running METviewer with Singularity on AWS only support generating batch plots on the command line; the GUI does not launch or function. Initial impression is some sort of port mapping issues.

In order to make image and other output files visible in the web UI the value of parameter 'url.output' should be changed to /metviewer_output. I made this change in Dockerfile and Dockerfile_for_Singularity files

[TatianaBurek]

To test, I rebuild the docker image and created singularity container from it. I was able to load the data and create and view the images using GUI

@TatianaBurek - I tried to rebuild the docker image with this command: docker build -t nwp-container-metviewer_singularity -f Dockerfile_for_Singularity .

But it failed with this error:

I am sure I am doing something silly...any ideas?

The Python libraries that are needed for METcalcpy/METviewer 4.0.2 have dependency issues that were resolved in the next version. Need to upgrade METviewer to v4.1, METcalcpy/METplotpy to 1.10 and add METdatadb

I tested building the new Dockerfile_for_Singularity -- success! Moving onto testing the loading and pulling up the GUI.

I committed the fix for mv_batch.sh. The container is ready for testing
