Add bzip support for PHP to support phantomjs-installer

[grasmash]

The default PHP bin on Drupal VM does not include bzip support. Adding it would require compiling PHP with bzip support, as it is not included by default. See http://php.net/manual/en/bzip2.installation.php.

This is currently required for use of https://github.com/jakoch/phantomjs-installer on Linux.

For Xenial, you can install bzip support via php-bz2 for PHP 7 (http://packages.ubuntu.com/xenial/php/php-bz2)

For Trusty, maybe http://stackoverflow.com/a/24988534/100134 ?

For phantomjs in particular, I know others using Drupal VM have used phantom before without running into issues with extra required packages... so I wonder, is there another way to install that doesn't require the dep, or is this something that changed recently?

I haven't touched phantom inside of Drupal VM for about 6 months, so my memory is fuzzy.

Trusty also now has php-bz2 for PHP 7

@geerlingguy ok, I'm assuming this addition to config.yml will be sufficient to install the package:

extra_packages:
  - php-bz2

Will report back on outcome.

@grasmash - Any luck? If that's all that's required, we could maybe add documentation in the Behat/Selenium guide http://docs.drupalvm.com/en/latest/extras/behat/

Works great for PHP7, but we will need a different solution for PHP5.*.

I think we have a good enough solution here—if you're using Selenium and no PhantomJS, there's no issue. If you want to use PhantomJS with PHP 7 (default), you need to modify your php_packages and add php-bz2. If you want to use it with PHP 5.6, you can modify php_pecl_extensions in your config.yml and add bz2 to that list (see docs here: https://github.com/geerlingguy/ansible-role-php-pecl).
