Progress toward issue #2003.

Use init containers to create configuration for Ceph mgrs. There is only
one init container in this design. The init container calls the Rook
binary to create Ceph config files which are then shared with the mds
daemon main container.
Once this init is run, the main mds daemon is run. Leaving room to use
the Ceph-versioned image in the future, call `ceph-mds --foreground ...`
to run the Ceph mds.
The refactor to using an init container also necessitated refactoring
the mdses replicaset implementation to a deployment-per-pod
implementation due to a chicken-egg problem. With a single container (in
the before times) the Rook binary was able to call the ceph-mds daemon
with an id generated from the pod name. Since the pod name is not known
before runtime, and the id is one of the few params that must be
specified to Ceph daemons on run, it is necessary to know the id
beforehand; thus the move to a deployment architecture following the
likes of the mon and mgr daemons.

remove all cosntraints that are not really needed from Gopkg.toml.
we should only be adding constraints that are direct dependencies
of the project and we require a specific version/revision of.
added a vendor.update makefile target that can be used to update
dependencies to the latest.

all vendor dependencies in Gopkg.toml now have constraints. this will
ensure that they do not float as people run `make vendor`. if you need
a new package be sure to change the contraint explicitly.

this commit updates dep to version 0.5, and adds a check during
CI runs that enforces that the vendor dependencies have not changed.
There is a now a makefile target `make vendor.check` that performs
this check. Also removed the requirement that PR run make vendor as
this will be done by CI.

Adds documentation about applying an imagePullSecret to a service
account to allow all pods spawned by the operator to have this
imagePullSecret. This is necessary to access an image
(e.g. ceph-agent) from a private/authenticated docker registry
without changing the current operator code.

Ceph expects to be able to reason about physical hardware / nodes.
Before this patch the NODE_NAME that was available referred to the pod
name. This patch exposes the underlying node name, pod, and pod
namespace for the ceph daemons to consume.

The NFS-Ganesha CRD will orchestrate highly available, scalable
Ganesha server pods as NFS gateways to the Ceph filesystem and
object stores already setup by rook.

Use init containers to create configuration for Ceph mgrs. There is only
1 init container in this design:
1. Using the Rook image, call the Rook binary to create Ceph config
files shared with the mgr daemgr container.
Once this init is run, the main mgr daemgr is run. Leaving room to use
the Ceph-versioned image in the future, call `ceph-mgr --foreground ...`
to run the Ceph mgr.

Add a 'test' package to the Ceph operator and define a test to verify
that containers produced by Rook-Ceph match what is expected. Because
this is for 'containers' and not strictly for 'ceph containers', this
could be moved a level up to the operator test package; however, if
other backends wish to use the container tests, they will likely need to
make modifications, and there is concern that this might make the Ceph
tests brittle.

Add a package called 'spec' to the Ceph operator to store resource
definition specs that are shared by all Ceph daemons.

Add functions for helping test Kubernetes volumes and volume mounts.
- Create functions for testing the existence of volumes/mounts by
name in a list of vols/mounts without needing to know the index of
the vol/mount in the list.
- Create functions for printing vols/mounts in a human-readable format
so that tests may output more useful errors.
- Create a test definition for ensuring that all the volumes a pod
provides and all the mounts from each pod container match. For each
volume, there must be at least one container which mounts the volume,
and for each mount, there must be a source volume.
