Brianna Poulos 56b62f9423 Update Volume Encryption Documentation
The castellan library has recently been updated to
use 'backend' instead of 'api_class' to configure
the backend that should be used.  This change updates
the volume encryption documentation to use the updated
configuration option instead of the deprecated one.
