Do not probe so aggressively which may lead to unnecessary restarts
@errordeveloper @mikedanese PTAL
I came across a case where etcd restarted about 5-10 times because the load was very high on the machine.
The load seems to have lead to that the `etcd` container occasionally didn't respond to the probe, which caused many restart and made the whole thing even worse.
Maybe we should remove the etcd probe totally? I don't know, what do you think?
This is at least a try to loosen the limits here...

Kubeadm: print information about certificates

kubeadm: default to using a private range for service subnet
We are currently using a subnet that is reserved for ISPs. Private network administrators don't control this space. Default to a subnet that private network administrators do control.

Use strongly-typed types.NodeName for a node name
We had another bug where we confused the hostname with the NodeName.
Also, if we want to use different values for the Node.Name (which is
an important step for making installation easier), we need to keep
better control over this.
A tedious but mechanical commit therefore, to change all uses of the
node name to use types.NodeName
We had another bug where we confused the hostname with the NodeName.
To avoid this happening again, and to make the code more
self-documenting, we use types.NodeName (a typedef alias for string)
whenever we are referring to the Node.Name.
A tedious but mechanical commit therefore, to change all uses of the
node name to use types.NodeName
Also clean up some of the (many) places where the NodeName is referred
to as a hostname (not true on AWS), or an instanceID (not true on GCE),
etc.
Currently the boostrap fails when a token is provided by the user
on `master init` and works when the token is generated. This is
because of a mismatch of how the token string in the kube-discovery
secret is encoded.
- start cleaning up `cmd/manual.go`
- refine progress and error messages
- add missing blank lines after the license headers
- run `gofmt -s -w`
- do not set fake cloud provider
- add a note on why we cannot remove `HostNetwork: true` from `kube-discovery` pod just yet
- taint master and use `role=master`, set tolerations and affinity for `kube-discovery`
- parametrise log-level flag for all components
