The new Amazon Metadata KMS provider uses a CMK stored in AWS KMS to
encrypt/decrypt the DEK which is stored in the volume metadata.

Amazon KMS expects a Secret with sensitive account and key information
in the Kubernetes Namespace where the Ceph-CSI Pods are running. It will
fetch the contents of the Secret itself.

These functions can now be re-used easier. The Amazon KMS needs to know

Incase of resync the image will get deleted, gets

Do resync if the image is in unknow or in error
state.
Check for the current image state for up+stopped
or up+replaying and also all peer site status
should be un up+stopped to confirm that resyncing
is done and image can be promoted and used.

After translating options from the ConfigMap into the common Vault

There is no need for each EncryptionKMS to implement the same GetID()
function. We have a VolumeEncryption type that is more suitable for
keeping track of the KMS-ID that was used to get the configuration of
the KMS.
This does not change any metadata that is stored anywhere.

GetKMS() is the public API that initilizes the KMS providers on demand.
Each provider identifies itself with a KMS-Type, and adds its own
initialization function to a switch/case construct. This is not well
maintainable.
The new GetKMS() can be used the same way, but uses the new kmsManager
interface to create and configure the KMS provider instances.
All existing KMS providers are converted to use the new kmsManager
plugins API.

The KMSProvider struct is a simple, extendable type that can be used to
register KMS providers with an internal kmsManager.
Helper functions for creating and configuring KMS providers will also be
located in the new kms.go file. This makes things more modular and

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

This new KMS is based on the (default) SecretsKMS, but instead of using

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.

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).

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.

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().

When images get resized/expanded, the additional space needs to be
allocated if the image was initially thick-provisioned. By marking the
image with a "thick-provisioned" key in the metadata, future operations
can check the need.
A missing "thick-provisioned" key indicates that the image has not been
thick-provisioned.
