4937e59c4d rbd: add backwards compatible encryption in NodeStageVolume
When a volume was provisioned by an old Ceph-CSI provisioner, the
metadata of the RBD image will contain `requiresEncryption` to indicate
a passphrase needs to be created. New Ceph-CSI provisioners create the
passphrase in the CreateVolume request, and set `encryptionPrepared`
instead.

When a new node-plugin detects that `requiresEncryption` is set in the
RBD image metadata, it will fallback to the old behaviour.

In case `encryptionPrepared` is read from the RBD image metadata, the
passphrase is used to cryptsetup/format the image.

ee79b22c97 rbd: move encryption function to encryption.go
This adds internal/rbd/encryption.go which will be used to include other
encryption functionality to support additional KMS related functions. It
will work together with the shared API from internal/util/kms.go.

dc81e001cf cleanup: remove unused MissingPassphrase error type
Storing a passphrase is now done while the volume is created. There is
no need to (re)generate a passphrase when it can not be found.

9b6c2117f3 rbd: set encryption passphrase on CreateVolume
Have the provisioner create the passphrase for the volume, instead of
doign it lazily at the time the volume is used for the 1st time. This
prevents potential races where pods on different nodes try to store
different passphrases at the (almost) same time.

a42c4b5855 util: convert VAULT_SKIP_VERIFY to "vaultCAVerify" KMS option
"VAULT_SKIP_VERIFY" is a standard Hashicorp Vault environment variable
(a string) that needs to get converted to the "vaultCAVerify"
configuration option in the Ceph-CSI format.

The value of "VAULT_SKIP_VERIFY" means the reverse of "vaultCAVerify",
this part was missing in the original conversion too.

d534ee9ce8 rbd: include rados-namespace when calling addRbdManagerTask()
It seems that calls to addRbdManagerTask() do not include the
rados-namespace in the image location. Functions calling
addRbdManagerTask() construct the image location themselves, but should
use rbdVolume.String() to include all the attributes.

The configuration option `EnvVaultInsecure` is expected to be a string,
not a boolean. By converting the bool back to a string (after
verification), it is now possible to skip the certificate validation
check by setting `vaultCAVerify: false` in the Vault configuration.

04644c1d58 rbd: enable mapping and unmapping from a network namespace
Make rbdplugin pod work in a non-initial network namespace (i.e. with
"hostNetwork: false") by skipping waiting for udev events when mapping
and unmapping images.  CSI use case is very simple: all that is needed
is a device node which is immediately fed to mkfs, so we should be able
to tolerate udev not being finished with the device just fine.

Add a new method to the EncryptionKMS interface so that resources can be
freed when EncryptionKMS instances get freed.

With the move to using the libopenstorage API, a temporary file needs to

vaultConnection type now removes this file.

The rbdVolume uses the EncryptionKMS type now, so call the new Destroy()
method from withing rbdVolume.Destroy().
