Docker Hub offers a way to pull official images without any project
prefix, like "docker.io/vault:latest". This does a redirect to the
images located under "docker.io/library".
By using the full qualified image name, a redirect gets removed while
pulling the images. This reduces the likelyhood of hittin Docker Hub
pull rate-limits.

Images that have an unqualified name (no explicit registry) come from
Docker Hub. This can be made explicit by adding docker.io as prefix. In
addition, the default :latest tag has been added too.

The BlockVolume PVC tests consume the example files that refer to
"centos:latest" without registry. This means that the images will get
pulled from Docker Hub, which has rate limits preventing CI jobs from
pulling images.

MD014 - Dollar signs used before commands without showing output
The dollar signs are unnecessary, it is easier to copy and paste and
less noisy if the dollar signs are omitted. Especially when the
command doesn't list the output, but if the command follows output
we can use `$ ` (dollar+space) mainly to differentiate between
command and its ouput.
scenario 1: when command doesn't follow output
```console
cd ~/work
```
scenario 2: when command follow output (use dollar+space)
```console
$ ls ~/work
file1 file2 dir1 dir2 ...
```

This patch with touch on the varuious other fields with in the storage class
yamls and label them with optional/required.
Signed-off-by: Prasanna Kumar Kalever <prasanna.kalever@redhat.com>
Obviously expecting a pool with name `rbd` or CephFS name `myfs`
will be a limitation, as the pool/fs is created by admin manually,
let them choose the name that suits their requirement and come back
edit it in the storage class.
Making the pool/fs name as required field will give more attention,
else with new users it will be mostly left unedited until one hit
the errors saying no pool/fs exists.
This patch clips-off the default pool/fs name and make it a mandatory
field.

Currently, the script does not deploy the driver singlehandedly;
As the vault creation needs to be done prior to that.
The script now includes the vault creation so that
one script can be sufficient to deploy the rbd driver.

Added support for RBD PVC to PVC cloning, below
commands are executed to create a PVC-PVC clone from
RBD side.
* Check the depth(n) of the cloned image if n>=(hard limit -2)
or ((soft limit-2) Add a task to flatten the image and return
about (to avoid image leak) **Note** will try to flatten the
temp clone image in the chain if available
* Reserve the key and values in omap (this will help us to
avoid the leak as it's not reserved earlier as we have returned
ABORT (the request may not come back))
* Create a snapshot of rbd image
* Clone the snapshot (temp clone)
* Delete the snapshot
* Snapshot the temp clone
* Clone the snapshot (final clone)
* Delete the snapshot
```bash
1) check the image depth of the parent image if flatten required
add a task to flatten image and return ABORT to avoid leak
(hardlimit-2 and softlimit-2 check will be done)
2) Reserve omap keys
2) rbd snap create <RBD image for src k8s volume>@<random snap name>
3) rbd clone --rbd-default-clone-format 2 --image-feature
layering,deep-flatten <RBD image for src k8s volume>@<random snap>
<RBD image for temporary snap image>
4) rbd snap rm <RBD image for src k8s volume>@<random snap name>
5) rbd snap create <cloned RBD image created in snapshot process>@<random snap name>
6) rbd clone --rbd-default-clone-format 2 --image-feature <k8s dst vol config>
<RBD image for temporary snap image>@<random snap name> <RBD image for k8s dst vol>
7)rbd snap rm <RBD image for src k8s volume>@<random snap name>
```
* Delete temporary clone image created as part of clone(delete if present)
* Delete rbd image

The quotes used in the comments seem to be non-ascii characters.
Replacing these with standard " makes the test pass again.
This problem occurred while running tests in a container based on the

* moves KMS type from StorageClass into KMS configuration itself
* updates omapval used to identify KMS to only it's ID without the type
why?
1. when using multiple KMS configurations (not currently supported)
automated parsing of kms configuration will be failing because some
entries in configs won't comply with the requested type
2. less options are needed in the StorageClass and less data used to
identify the KMS

- adds proposal document for PVC encryption from PR448
- adds per-volume encription by generating encryption passphrase
for each volume and storing it in a KMS
- adds HashiCorp Vault integration as a KMS for encryption passphrases
- avoids encrypting volume second time if it was already encrypted but
no file system created
- avoids unnecessary checks if volume is a mapped device when encryption
was not requested
- prevents resizing encrypted volumes (it is not currently supported)
- prevents creating snapshots from encrypted volumes to prevent attack
on encryption key (security guard until re-encryption of volumes
implemented)

Fedora 26 has been End-Of-Life for a long time already, is should not be
used anymore. Instead use the latest CentOS image that gets regular
updates. The Ceph base image used by Ceph-CSI is also based on CentOS,
so uses would be familiar with the available tools.
Also use "sleep infinity" instead of a weird 'tail -f /dev/null' hack.

Adds encryption in StorageClass as a parameter. Encryption passphrase is
stored in kubernetes secrets per StorageClass. Implements rbd volume
encryption relying on dm-crypt and cryptsetup using LUKS extension
The change is related to proposal made earlier. This is a first part of
the full feature that adds encryption with passphrase stored in secrets.

The storage class already takes MountOptions(MountFlags), these are the
bind mount options. Some of these options may not be recognised by the
cephfs mount. Hence added a new parameterin Storage Class for
- cephfs kernel mount options,
- ceph-fuse mount options
Ceph kernel mount options are different from ceph-fuse options, hence
added two different parameters.

Deployment behaves better when a node gets disconnected
from the rest of the cluster - new provisioner leader
is elected in ~15 seconds, while it may take up to

RBD plugin needs only a single ID to manage images and operations against a
pool, mentioned in the storage class. The current scheme of 2 IDs is hence not
needed and removed in this commit.
Further, unlike CephFS plugin, the RBD plugin splits the user id and the key
into the storage class and the secret respectively. Also the parameter name
for the key in the secret is noted in the storageclass making it a variant and
hampers usability/comprehension. This is also fixed by moving the id and the key
to the secret and not retaining the same in the storage class, like CephFS.
