Ian Wienand 6c077d7c2a Turn down pkg-map and hook copy tracing output
This is a lot of very low value noise in the logs as these iterate
through all the elements (often doing nothing).  Turn it down and add
an echo so we just see what elements it is working on.

=======
pkg-map
=======
Map package names to distro specific packages.

Provides the following:

 * bin/pkg-map::

    usage: pkg-map [-h] [--element ELEMENT] [--distro DISTRO]

    Translate package name to distro specific name.

    optional arguments:
      -h, --help         show this help message and exit
      --element ELEMENT  The element (namespace) to use for translation.
      --distro DISTRO    The distro name to use for translation. Defaults to
                         DISTRO_NAME
      --release RELEASE  The release to use for translation.  Defaults to
                         DIB_RELEASE

 * Any element may create its own pkg-map JSON config file using the
   one of 4 sections for the release/distro/family/ and or default.
   The family is set automatically within pkg-map based on the
   supplied distro name. Families include:

     + redhat: includes centos, fedora, and rhel distros
     + debian: includes debian and ubuntu distros
     + suse: includes the opensuse distro

   The release is a specification of distro; i.e. the distro and
   release must mach for a translation.

   The most specific section takes priority.

   An empty package list can be provided.

   Example for Nova and Glance (NOTE: using fictitious package names
   for Fedora and package mapping for suse family to provide a good
   example!)

   Example format::

    {
      "release": {
        "fedora": {
          "23": {
            "nova_package": "foo" "bar"
          }
        }
      },
      "distro": {
        "fedora": {
          "nova_package": "openstack-compute",
          "glance_package": "openstack-image"
        }
      },
      "family": {
        "redhat": {
          "nova_package": "openstack-nova",
          "glance_package": "openstack-glance"
        },
        "suse": {
          "nova_package": ""
        }
      },
      "default": {
        "nova_package": "nova",
        "glance_package": "glance"
      }
    }

   Example commands using this format:

   pkg-map --element nova-compute --distro fedora nova_package

   Returns: openstack-compute

   pkg-map --element nova-compute --distro rhel nova_package

   Returns: openstack-nova

   pkg-map --element nova-compute --distro ubuntu nova_package

   Returns: nova

   pkg-map --element nova-compute --distro opensuse nova_package

   Returns:

 * This output can be used to filter what other tools actually install
   (install-packages can be modified to use this for example)

 * Individual pkg-map files live within each element. For example
   if you are created an Apache element your pkg-map JSON file
   should be created at elements/apache/pkg-map.
