Since a guest-assisted disk snapshot is performed on the compute that the instance is running on, there are only certain states that the instance can be in to perform this operation. For example, if the instance is shelved_offloaded then the instance does not have a host and we can't cast to a compute to perform the snapshot. Given how unrestrictive this API was before, the only restriction we place on the state is that the instance does not have a task_state set. We allow any vm_state for performing the operation as long as there is a host and no task_state. As noted in the code, we'd normally return a 409 in this case but according to our microversion docs [1] that would be a new error code and require a version bump, so this change just uses 400 and leaves a TODO to make this 409 in a later mass return code update microversion.
