Remove duplicated code which was setting up grpc client with common
method. Should have no functional changes otherwise.
Add args len check where missing.

* refactor(init): Allow kubeadm init on controlplane
This shifts the cluster formation from init(bootstrap) and join(control plane)
to init(control plane).
This makes use of the previously implemented initToken to provide a TTL for
cluster initialization to take place and allows us to mostly treat all control
plane nodes equal. This also sets up the path for us to handle master upgrades
and not be concerned with odd behavior when upgrading the previously defined
init node.
To facilitate kubeadm init across all control plane nodes, we make use of the
initToken to run `kubeadm init phase certs` command to generate any missing
certificates once. All other control plane nodes will attempt to sync the
necessary certs/files via all defined trustd endpoints and being the startup
process.

This returns list of all the services registered, with their current
status, past events, health state, etc.
New CLI is `osctl service [<id>]`: without `<id>` it prints list of all
the services, with specific `<id>` it provides details for a service.
I decided to create "parallel" data structures in protobuf as Go
structures don't map nicely onto what protoc generates: pointers vs.
values, additional fields like mutexes, etc. Probably there's a better
approach, I'm open for it.
For CLI, I tried to keep CLI stuff in `cmd/` package, and I also created
simple wrapper to remove duplicated code which sets up client for each
command.
Examples:
```
$ osctl service
SERVICE STATE HEALTH LAST CHANGE LAST EVENT
containerd Running OK 21s ago Health check successful
kubeadm Running ? 2s ago Started task kubeadm (PID 280) for container kubeadm
kubelet Running ? 0s ago Started task kubelet (PID 383) for container kubelet
ntpd Running ? 14s ago Started task ntpd (PID 129) for container ntpd
osd Running ? 14s ago Started task osd (PID 126) for container osd
proxyd Waiting ? 14s ago Waiting for conditions
trustd Running ? 14s ago Started task trustd (PID 125) for container trustd
udevd Running ? 14s ago Started task udevd (PID 130) for container udevd
```
```
$ osctl service proxyd
ID proxyd
STATE Running
HEALTH ?
EVENTS [Preparing]: Running pre state (22s ago)
[Waiting]: Waiting for conditions (22s ago)
[Preparing]: Creating service runner (6s ago)
[Running]: Started task proxyd (PID 461) for container proxyd (6s ago)
```

This implements insecure over-file-socket gRPC API for init with two
first simplest APIs: reboot and shutdown (poweroff).
File socket is mounted only to `osd` service, so it is the only service
which can access init API. Osd forwards reboot/shutdown already
implemented APIs to init which actually executes these.
This enables graceful shutdown/reboot with service shutdown, sync, etc.
