Upgrade json gem version to latest

[dandunckelman]

After further discussion in #267, I've recreated the PR since I deleted the original fork, derp. The only difference between that PR and this one is that I updated to Ruby v2.2.3, whereas the other PR used v2.2.2.

I wanted to install this plugin with the latest Vagrant (v.1.8.1 when I went to https://www.vagrantup.com/downloads.html) but received errors when bundle tries installing the json gem v1.7.7. So, I figured I'd try getting the install to work with the latest JSON gem.

To do this, I performed the following on an Ubuntu v14.04 VM with Ruby v2.2.3 (via RVM):

• Fork repo

• Clone repo to my box

  git clone https://github.com/dandunckelman/vagrant-openstack-provider.git
  

• Create topic branch

  cd vagrant-openstack-provider
  git checkout -b upgrade-json-dependency
  

• Setup Ruby environment (since I use RVM):

  cd source/
  echo "2.2.3" > .ruby-version
  echo "vagrant-openstack-provider" > .ruby-gemset
  

• Install specific bundler version (since the Vagrant v1.7.4 gem requires bundler (<= 1.10.5, >= 1.5.2))

  gem install bundler -v 1.10.5
  

• Install gems

  bundle
  

• Run tests

  bundle exec rake
  

• Build as a gem

  bundle exec rake build
  

• Install plugin from gem

  cd ../../my-vagrant-project/
  vagrant plugin install ../vagrant-openstack-provider/source/pkg/vagrant-openstack-provider-0.7.0.gem
  

Then the install worked as expected. I assume that this would fix the following issues: #265 &
#266

Should I update .travis.yml to do the following or something similar?

• Add 2.2.3 to the rvm list
• Add VAGRANT_VERSION=v1.8.1 BUNDLER_VERSION=1.10.5 to the matrix list

Verified as working on Fedora 23 using the latest vagrantup.com vagrant package and system Ruby to build the updated .gem:

git clone https://github.com/dandunckelman/vagrant-openstack-provider.git
cd vagrant-openstack-provider/source
git checkout upgrade-json-dependency
sudo dnf install ruby-devel redhat-rpm-config
bundle
bundle exec rake build
vagrant plugin install pkg/vagrant-openstack-provider-0.7.0.gem

Verified on Ubuntu 14.04 with latest vagrant, works

Confirmed as working with the vagrant-1.8.1-1.x86_64 rpm (vagrantup; not fedora's native packaging) on Fedora 23.
