Add GDAL Java bindings

Depends on https://github.com/geotrellis/geotrellis/pull/902.

This changeset adds the GDAL Java bindings through the [azavea.libgdal-java](https://github.com/azavea/ansible-libgdal-java) Ansible role. The role is added as a dependency of the `common` role, so that all nodes in the cluster contain the bindings.

In addition to adding the GDAL Java bindings, I had to make a few tweaks to the development environment to get things to work:

- Enhance `local_ip` function in the `Vagrantfile` so that it supports Linux
- Remove the `eth` variable definition from `all.yml` and add an entry to `development.yml` and `production.yml` with different defaults for each
- Expand list of `no_proxy` hosts because of issues Polipo is having trying to cache some of the Java package repositories

Tested in the Vagrant development environment with:

```
$ cd ~/geotrellis
$ ./sbt
root > project gdal
gdal > run

gdalinfo
Usage: gdalinfo [options] <file>

  --mm
        Force computation of the actual min/max values for each band in the dataset.
  --stats
        Read and display image statistics. Force computation if no statistics are stored in an image.
  --approx_stats
        Read and display image statistics. Force computation if no statistics are stored in an image. However, they may be computed based on overviews or a subset of all tiles. Useful if you are in a hurry and don't want precise stats.
  --hist
        Report histogram information for all bands.
  --nogcp
        Suppress ground control points list printing. It may be useful for datasets with huge amount of GCPs, such as L1B AVHRR or HDF4 MODIS which contain thousands of them.
  --noct
        Suppress printing of color table.
  --nomd
        Suppress metadata printing. Some datasets may contain a lot of metadata strings.
  --norat
        Suppress printing of raster attribute table.
  --checksum
        Force computation of the checksum for each band in the dataset.
  --mdd <value>
        Report metadata for the specified domain. Starting with GDAL 2.0, 'all' can be used to report metadata in all domains.
  <file>
        Path to a GDAL supported raster dataset.
