* Using Fedora 21 as the base box
* Discover the active network interfaces in the box to avoid hardcoding
them in configuration.
* Use the master IP for the certificate.
The default Fedora 21 image requires some manual networking fixup that
breaks Fedora 22. This change ensures that the fixup in question is run
only for Fedora 21.
It looks like api_servers finally won this battle. Kill off the
last remaining places passing it, but allow the kubelet Salt to
accept apiservers for a period of time.
(This was bothering my OCD.)
* Have a single config file that mirrors other cluster providers
* Warn users not to use 'vagrant up' directly
* Allow 'extra' parameters to the docker daemon. Fixes#2685
* Renumbers things so that they are more sane. Master/minions are 10.245.1.x, container subnets are 10.246.x.1/24, portal is 10.247.0.0/16
Quoting is hard. When writing strings into YAML files, wrap them in single quotes. Also escape any embedded single quotes in those strings via a double signle quote ('').
The workaround was not needed, as salt-minion was always correctly
started in the Vagrant minion setup.
The issue reported in #270 was clearly specific do System V style init
scripts and will not affect systemd.
Also remove the inaccurate comment from provision-master.sh, since -X
was not even really in use there.
Tested:
- Performed 3 full `vagrant up` and `vagrant destroy -f` cycles with at
least 3 minions and up to 6 minions in one case. Checked that
salt-minion was up in each of the minions using a `systemctl status
salt-minion` command.
- Started nginx on the cluster using cluster/kubecfg.sh, confirmed it
was up with `list /pods` and confirmed it was reachable using wget on
port 8080 of the minions.

The `which` command in Fedora 20 (differently from the one in Debian)
prints to stderr when the binary is not found. Redirect both stdout and
stderr to /dev/null to prevent messages from being printed by `which`.
Check whether the binary exists or not by the exit status of `which`
(non-zero means the binary does not exist) instead of checking for empty
output.
Tested:
- Started a Vagrant cluster with `vagrant up` and confirmed these
messages were gone. Checked master and minions for Kubernetes
components using the systemd status commands.
- Confirmed that the same error message for salt-minion is also
suppressed from the output with this patch.
Fixes: Issue #1079
