This commit adds capability to `metadata` encryption
to be able to fetch `encryptionPassphrase` from user
specified secret name and namespace(if not specified,
will default to namespace where PVC was created).
This behavior is followed if `secretName` key is found
in the encryption configuration else defaults to fetching
`encryptionPassphrase` from storageclass secrets.

This commit returns actual error returned by the go-ceph API
to the function GetPoolName(..) instead of just returning
ErrPoolNotFound everytime there is error getting the pool id.
There is a issue reported in which the snapshot creation
takes much more time to reach True state
(i.e., between 2-7 mins) and keeps trying to create with
below error though pool is present:
rpc error: code = NotFound desc = pool not found: pool ID (21)
not found in Ceph cluster.
Since we cannot interpret the actual error for the delay in
snapshot creation, it is required to return the actual error
as well so that we can uderstand the reason.

It helps to get a stack trace when debugging issues. Certain things are
considered bugs in the code (like missing attributes in a struct), and
might cause a panic in certain occasions.
In this case, a missing string will not panic, but the behaviour will
also not be correct (DEKs getting encrypted, but unable to decrypt).
Clearly logging this as a BUG is probably better than calling panic().

The new StoreCryptoPassphrase() method makes it possible to store an
unencrypted passphrase newly encrypted in the DEKStore.
Cloning volumes will use this, as the passphrase from the original
volume will need to get copied as part of the metadata for the volume.

After translating options from the ConfigMap into the common Vault
parameters, the generated configuration is not used. Instead, the
untranslated version of the configuration is passed on to the
vaultConnection initialization function, which then can detects missing
options.
By passing the right configuration to the initializatino function,
things work as intended.

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.
Signed-off-by: Niels de Vos <ndevos@redhat.com>
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
better maintainable.

This new KMS is based on the (default) SecretsKMS, but instead of using
the passphrase for all volumes, the passphrase is used to

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.
Signed-off-by: Niels de Vos <ndevos@redhat.com>
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).

Prepared for an enhanced API to communicate with a KMS and keep the DEK

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.
Signed-off-by: Niels de Vos <ndevos@redhat.com>
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.

"VAULT_SKIP_VERIFY" is a standard Hashicorp Vault environment variable
(a string) that needs to get converted to the "vaultCAVerify"
