dm vdo: add repair of damaged vdo volumes

Browse Source 
When a vdo is restarted after a crash, it will automatically attempt to
recover from its journals.

If a vdo encounters an unrecoverable error, it will enter read-only mode.
This mode indicates that some previously acknowledged data may have been
lost. The vdo may be instructed to rebuild as best it can in order to
return to a writable state. Although some data may be lost, this process
will ensure that the vdo's own metadata is self-consistent.
