rbdVolumes can have several resources that get allocated during its
usage. Only destroying the IOContext may not be suffiecient and can
cause resource leaks.
Use rbdVolume.Destroy() when the rbdVolume is not used anymore.

Connections are reference counted, so just assigning the connection to
an other object for re-use is not correct. This can cause connections to
be garbage collected while something else is still using it.

Currently, in rbd snapshot restore and volume clone E2E we
are not checking any data consistency after doing snapshot
restore or volume clone. Hence, this PR writes the data in
the PVC and checks the checksum of the file and verify it with
the snapshot or cloned PVC.

Because rbdVolume and rbdSnapshot are very similar, they can be based
off a common struct rbdImage that contains the common attributes and
functions.
This makes it possible to re-use functions for snapshots, and prevents
further duplication or code.

The rbdSnapshot and rbdVolume structs have many common attributes. In
order to combine these into an rbdImage struct that implements shared
functionality, having the same attribute for the ID makes things much
easier.

Update the emcrypted PVC implementation doc with references to the new
EncryptedKMS, DEKStore and VolumeEncryption types.
Signed-off-by: Niels de Vos <ndevos@redhat.com>
This new KMS is based on the (default) SecretsKMS, but instead of using
the passphrase for all volumes, the passphrase is used to
encrypt/decrypt a Data-Encryption-Key that is stored in the metadata of
the volume.

Signed-off-by: Niels de Vos <ndevos@redhat.com>
The new SecretsMetadataKMS provider encrypts/decrypts DEKs as they are
stored in the metadata of volumes. The encryption/decryption uses
golang.org/x/crypto/scrypt to generate the encryption key from a
passphrase.
While vendoring golang.org/x/crypto, already vendored sub-packages have
been updated.

By adding these methods, a KMS can explicitly encrypt/decrypt the DEK if
there is no transparent way of doing so.
Hashicorp Vault encrypts the DEK when it it stored, and decrypts it when
fetched. Therefor there is no need to do any encryption in this case.

NewVolumeEncryption() will return an indication that an alternative
DEKStore needs to be configured in case the KMS does not support it.
setKMS() will also set the DEKStore if needed, so renaming it to
configureEncryption() makes things clearer.

Use DEKStore API for Fetching and Storing passphrases.
Drop the fallback for the old KMS interface that is now provided as
DEKStore. The original implementation has been re-used for the DEKStore
interface.
This also moves GetCryptoPassphrase/StoreNewCryptoPassphrase functions
to methods of VolumeEncryption.

DEKStore is a new interface that will be used for Storing and Fetching
DEKs. The existing implementations for KMS already function as a
DEKStore, and will be updated to match the interface.
By splitting KMS and DEKStore into two components, the encryption
configuration for volumes becomes more modular. This makes it possible
to implement a DEKStore where the encrypted DEK for a volume is stored
in the metadata of the volume (RBD image).

Prepare for grouping encryption related functions together. The main
rbdVolume object should not be cluttered with KMS or DEK procedures.

Prepared for an enhanced API to communicate with a KMS and keep the DEK
storage separate. The crypto.go file is already mixed with different
functions, so moving the KMS part into its own file, just like we have
for Hashicorp Vault KMS's.

For NodeUnstageVolume its a two step process,
first unmount the volume and than unmap the volume.
Currently, we are logging only after rbd unmapping is done.
sometimes it becomes difficult to debug with above logging
whether more time is spent in unmount or unmap.
This commits adds one more debug log after unmount is done.
with this we can identify where exactly more time is spent
by looking at the logs.

The stripe-size is the most efficient size to write to RBD images.
However, not all images are a multiple of stripe-size large. That means
thick-provisioning would not allocate the full image, and the process
might even fail.
This adds a 50 MB PVC to test the process, 100 MB is coincidentally a
multiple of the (default 4 MB) stripe-size, 50 MB is not.

It seems that writing more than 1 GiB per WriteSame() operation causes
an EINVAL (22) "Invalid argument" error. Splitting the writes in blocks
of maximum 1 GiB should prevent that from happening.
Not all volumes are of a size that is the multiple of the stripe-size.
WriteSame() needs to write full blocks of data, so in case there is a
small left-over, it will be filled with WriteAt().
