Mirror-snapshots can also be automatically created on a
periodic basis if mirror-snapshot schedules are defined.
The mirror-snapshot can be scheduled globally, per-pool,
or per-image levels. Multiple mirror-snapshot schedules
can be defined at any level.
To create a mirror-snapshot schedule with rbd, specify
the mirror snapshot schedule add command along with an
optional pool or image name; interval; and optional start time:
The interval can be specified in days, hours, or minutes
using d, h, m suffix respectively. The optional start-time
can be specified using the ISO 8601 time format. For example:
```
$ rbd --cluster site-a mirror snapshot schedule
add --pool image-pool --image image1 24h 14:00:00-05:00
```

In case restoring a snapshot of a thick-PVC failed during DeepCopy(),
the image will exist, but have partial contents. Only when the image has
the thick-provisioned metadata set, it has completed DeepCopy().
When the metadata is missing, the image is deleted, and an error is
returned to the caller. Kubernetes will automatically retry provisioning
on the ABORTED error, and the restoring will get restarted from the

RbdImageName holds the name of the parent from

is independent of snapshot and it can be deleted

to check the rbd image details.

This commit returns actual error returned by the go-ceph API
to the function GetPoolName(..) instead of just returning
ErrPoolNotFound everytime there is error getting the pool id.
There is a issue reported in which the snapshot creation
takes much more time to reach True state
(i.e., between 2-7 mins) and keeps trying to create with
below error though pool is present:
rpc error: code = NotFound desc = pool not found: pool ID (21)
not found in Ceph cluster.
Since we cannot interpret the actual error for the delay in
snapshot creation, it is required to return the actual error
as well so that we can uderstand the reason.

In golang world, if you split an empty string that does not contain
the seperator, you get an array with one empty string. This results
in volumes failing to mount with "invalid feature " (note extra space
because it's trying to check if 'empty string' is a valid feature).
This patch checks if the string is empty, and if so, it just decides
to skip the entire validation and returning nothing.
