If instance creation fails at the PreReq phase, no machine is created at the Ganeti backend. The event daemon picks up OP_INSTANCE_CREATE failing, and the creates the relevant notification and Synnefo instance is marked in ERROR.

However, it can never be removed: DELETE /servers/id issues OP_INSTANCE_REMOVE at the backend, which cannot complete successfully,
since the logic layer requires notification of successful execution of OP_INSTANCE_REMOVE to mark an instance as deleted in the DB,
after the changes made in #721.

Possible fix: if an OP_INSTANCE_REMOVE fails with ECODE_NOENT = "unknown_entity", the Ganeti instance is no longer there, and the Synnefo instance should be marked as deleted.

Handle removing machines in ERROR properly

Set the VM deleted flag when receiving a failure notification for a Ganeti
OP_INSTANCE_REMOVE operation, if the server is in ERROR state, since no
corresponding Ganeti instance backend exists in this case. Fixes #799.
