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.

Uses github.com/libopenstorage/secrets to communicate with Vault. This
removes the need for maintaining our own limited Vault APIs.
By adding the new dependency, several other packages got updated in the
process. Unused indirect dependencies have been removed from go.mod.
