This reverts commit 51f4e658.

Change to support multiple inventory path led to Vagrant environment not
getting a default group_vars in it's inventory path. Using sample as the
default path if none specified.

Fix issue #2541

Depending on the VM configuration, vagrant may either use 'rsync' or
vboxfs for populating the working directory to the VM. However, vboxfs
means that any files created by the VM will also be present on the host.
As such, lets be explicit and always use 'rsync' to copy the directory
to the VM so we can keep the host copy clean. Moreover, the default
rsync options include '--copy-links' and this breaks rsync if there are
missing symlinks in the working directory like the following one:

Error: symlink has no referent:
"/home/user/kubespray/contrib/network-storage/glusterfs/group_vars"

As such, we override the default options to drop --copy-links.

Add support for provisioning kubespray on openSUSE Tumbleweed virtual
machines.

Add support for provisioning kubespray on openSUSE Leap 42.3 virtual
machines.

The default path assumes that the vagrant dir is called 'inventory'.
With custom defined inventory dirs that are not called 'inventory' this
fails to create the correct symlink under .vagrant.d.

The "centos/7" box is the official centos box and supports all the major
providers:

virtualbox Externally hosted (cloud.centos.org)
vmware_desktop Externally hosted (cloud.centos.org)
libvirt Externally hosted (cloud.centos.org)
hyperv Externally hosted (cloud.centos.org)

Where  bento/centos-7.3 only supports:

parallels Hosted by Vagrant Cloud (570 MB)
virtualbox Hosted by Vagrant Cloud (525 MB)
vmware_desktop Hosted by Vagrant Cloud (608 MB)

When testing deployments of SDS, it is quite useful to get a Kubernetes
env with nodes having dedicated drives.
You can now enable this by setting: kube_node_instances_with_disks: true

Also you can chose the amount of drives per machine and their respective
size:

* kube_node_instances_with_disks_number: 10
* kube_node_instances_with_disks_size: "20G"

Updates based on feedback

Simplify checks for file exists

remove invalid char

Review feedback. Use regular systemd file.

Add template for docker systemd atomic

The Vagrantfile is setup to use flannel.  The default network
was changed to Calico (#1031).  However, the Vagrantfile was
not updated to reflect this.  Ensuring the Vagrantfile remains
functional on master, until someone decides to make it work
with Calico.

* Git ignore the user controlled config.rb.
* Ability to better control the number of instances running.

When download_run_once=True it will try to first download images to host
running vagrant, then upload the images from vagrant host to the vagrant
vms. While trying to upload the images it will ask for a the vagrant
linux user password.

For small environments this behaviour is unnecessary hence changing the
default to download_run_once=False inside the Vagrantfile seems like a
good fix.

[c7b00cae] Use tar+register instead of copy/slurp for distributing tokens and certs

Related bug: https://github.com/ansible/ansible/issues/15405

Uses tar and register because synchronize module cannot sudo on the
remote side correctly and copy is too slow.

This patch dramatically cuts down the number of tasks to process
for cert synchronization.

If skip_dnsmasq is set, it will still not set up dnsmasq

Fixes Ubuntu 14.04 deployment of etcd.

using a shared folder can cause race conditions for the download
role as it tries to download files on all the nodes to the same
shared path.  This adds a flag to run the tasks in the download
role on just one node.

I accidently left in the old download URL for coreos
even after I switched the box name to be ubuntu, it
worked fine for me because I already had that box
locally so it didn't try to download.  This should
resolve this by using the official bento/ubuntu-14.04
box which is a nice minimal image.

We also allow the default behaviour of sharing folder to VMs

By doing this we can stage our download files in a shared location
and speed up subsequent runs significantly.

Finally will create more verbose documentation.

* set flannel backend type to `host-gw`
* set flannel interface to be eth1 ip

This allows you to simply run `vagrant up` to get a 3 node HA cluster.

* Creates a dynamic inventory and uses the inventory/group_vars/all.yml
* commented lines in inventory.example so that ansible doesn't try to use it.
* added requirements.txt to give easy way to install ansible/ipaddr
* added gitignore files to stop attempts to save unwated files
* changed `Check if kube-system exists` to `failed_when: false` instead of
`ignore_errors`
