Replaced ansible_ssh_host with ansible_host in sample inventory file and fixed usage of bastion

* Raise limits for weave

* Adjust weave limits

Vagrantfile: Fix default inventory path.

Kubespray should not install any helm charts. This is a task
that a user should do on his/her own through ansible or another
tool. It opens the door to wrapping installation of any helm
chart.

move when condition to main.yml

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.

The RPM file that's provided by upstream can be used for SUSE
distributions as well. Moreover we simplify the playbook to use
the 'package' module to install packages across different distros.

Add path for certificate location for SUSE distributions. Also make sure
the 'update-ca-certificates' command is executed on SUSE hosts as well.

If the 'docker' package is already installed, then the handlers will not
run and the service will not be (re-)started. As such, lets make sure
that the service is started even if the packages are already installed.

Add support for installing Docker on SUSE distributions. The Docker
repository at https://yum.dockerproject.org/repo/main/ does not support
recent openSUSE distributions so the only alternative is to use the
packages from the distro repositories. This however renders the
'docker_version' Ansible variable useless on SUSE.

The openssl package on Tumbleweed is actually a virtual package covering
openssl-1.0.0 and openssl-1.1.0 implementations. It defaults to 1.1.0 so
when trying to install it and openssl-1.0.0 is installed, zypper fails
with conflicts. As such, lets explicitly pull the package that we need
which also updates the virtual one.

Add support for installing package dependencies and refreshing metadata
on SUSE distributions

openSUSE Tumbleweed is having the same problems with CoreOS when it
comes to using the hostname ansible module (#1588, #1600) so we need
to apply a similar workaround.

Install some required packages when running on SUSE distributions.

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.

Changed from OS_PROJECT_ID to OS_PROJECT_NAME.

All checks test if this is defined meaning there is no way to undefine it.
