Moved from #203 by @RafnexJr

While installing Malcolm in an environment running behind a proxy problems with the Arkime container occured. The script initarkime.sh tries to download/update the geo data but fails behind a proxy. Even when the proxy is configured as environment variable in the docker-compose file. There's no error message the script just won't return anything after line 11.

To reproduce

Steps to reproduce the behavior:

• Install according to documentation

• Set proxy environment variables HTTP_PROXY and HTTPS_PROXY on the file-monitor and arkime container

• Start Malcolm with the script

Expected behavior

I would expect that the container would use the proxy specified in the HTTP(S)_PROXY env variable to get the geo data and report an error if something went wrong.
