Add scicat_client to the datacatalog module.

The script is based off the scicat_client-0.1.0 anaconda environment.
Conda does not need to be activated to run, so the pmodule simple
symlinks the entrypoint to the module bin.

+# Datacatalog
+
+## Overview 
+
+This module provides tools to interface with the Data Catalog (discovery.psi.ch).
+
+## Installation
+
+Run `./build <VERSION>` to install the latest version. This downloads the
+latest versions of the datasetIngestor, datasetRetriever, and datasetArchiver
+tools. Note that the downloads are not versioned, so make sure that the current
+variant matches the installed binaries.
+
+The `scicat_client` script is also installed. This is maintained as an anaconda
+environment, then symlinked into the datacatalog pmodule. Anaconda hard-codes
+the correct python interpreter, so all dependencies should resolve even though
+the conda module is not activated. See
+Programming/anaconda/2019.07/conda-env-defs/scicat_client for environment
+installation details.

-## Installation
-
-For the module we use a RPM distributed by HP.
-
-1. Create new directory `/opt/psi/System/mxm/VERSION_merlin`
-1. Download RPM from https://downloads.linux.hpe.com/sdr/repo/mlnx_ofed/RedHatEnterpriseServer/
-1. Unpack RPM with `rpm2cpio RPM | cpio -i --make-dirs` somewhere
-1. copy all files from `opt/mellanox/mxm` to the module directory
-1. adapt directories in `lib/pkg-config/mxm.pc`
-1. add new variant to `files/variants`
-1. run the build-script to install the modulefile and to set the release
- 
-
-> **Note:** The shared library `libmxm.so`provided by the RPMs for RHEL 6 cannot be used to compile other software.
-They requiry GLIBC >= 2.14, but on RHEL 6 only 2.12 is installed!
