Prior to Queens any attempt to swap between encrypted volumes would
result in unencrypted data being written to the new volume. This
unencrypted data would then be overwritten the next time the volume was
attached to an instance as Nova no longer identified the volume as
encrypted, resulting in the volume being reformatted.
This stable only change uses limited parts of the following changes to
block all swap_volume attempts with encrypted volumes prior to Queens
where this was resolved by Ica323b87fa85a454fca9d46ada3677f18 and also
blocked when using QEMU to decrypt LUKS volumes by
Ibfa64f18bbd2fb70db7791330ed1a64fe61c1.

The request context is provided to swap_volume in order to look up the
encryption metadata of a volume.

Attempts to swap from an encrypted volume are blocked with a
NotImplementedError exception raised.

Attempts to swap from an unencrypted volume to an encrypted volume are
also blocked with a NotImplementedError exception raised.

The serial of a volume is used as the id if connection_info for the
volume doesn't contain the volume_id key. Required to avoid bug #1746609.
