Add mount override for /etc/cvmfs/default.d/90-local.conf

[djw8605]

The default CVMFS package installs /etc/cvmfs/default.d/50-cern.conf which defines the config repo. The only place that a config repo can defined is default.local or in default.d directory, so to change the config repo (for example, to use the OSG config repo) you must add a new file, to be read after 50-cern.conf to the default.d directory.

An example is shown in the values.yaml file, but also here for what would be required to use the OSG config repo.

  cvmfs-csi-default-d:
    90-local.conf: |
      CVMFS_SEND_INFO_HEADER=yes
      CVMFS_KEYS_DIR=/etc/cvmfs/keys/opensciencegrid.org
      CVMFS_USE_GEOAPI=yes
      CVMFS_CONFIG_REPOSITORY=config-osg.opensciencegrid.org
      CVMFS_CONFIG_REPO_REQUIRED=yes
      CVMFS_FALLBACK_PROXY="http://cvmfsbproxy.fnal.gov:3126;http://cvmfsbproxy.cern.ch:3126"

@djw8605 this lgtm. @1602077 is back from holidays next Tuesday, if that's ok i would wait for him to merge and do a release right after.

That timeframe works for me.
