582d004ca5 util: store EnvVaultInsecure as string, not bool
The configuration option `EnvVaultInsecure` is expected to be a string,
not a boolean. By converting the bool back to a string (after
verification), it is now possible to skip the certificate validation
check by setting `vaultCAVerify: false` in the Vault configuration.

df81022349 rbd: add support for VAULT_SKIP_VERIFY in KMS ConfigMap
When the KMS VaultTokens is configured through a Kubernetens ConfigMap,
the `VAULT_SKIP_VERIFY` option was not taken into account. The option
maps to the `vaultCAVerify` value in the configuration file, but has the
reverse meaning.

04644c1d58 rbd: enable mapping and unmapping from a network namespace
Make rbdplugin pod work in a non-initial network namespace (i.e. with
"hostNetwork: false") by skipping waiting for udev events when mapping
and unmapping images.  CSI use case is very simple: all that is needed
is a device node which is immediately fed to mkfs, so we should be able
to tolerate udev not being finished with the device just fine.

8f91c672d4 util: add EncryptionKMS.Destroy()
Add a new method to the EncryptionKMS interface so that resources can be
freed when EncryptionKMS instances get freed.

With the move to using the libopenstorage API, a temporary file needs to
store the optional CA certificate. The Destroy() method of the
vaultConnection type now removes this file.

The rbdVolume uses the EncryptionKMS type now, so call the new Destroy()
method from withing rbdVolume.Destroy().

is created or not, currently we are checking if the key is present
in a map and localClusterStatelocalClusterState.resizeSupported
is set to false to call ceph fs subvolume resize to check command is
supported or not, if a structure is  initialized all its members
are set to default value. so we will never going to check the
ceph fs subvolume  resize command is supported in backend or not, we are
always using ceph fs subvolume create to resize subvolume. in some
ceph version ceph fs subvolume create wont work to resize a subvolume.

proper handling of this scenario.

66aa595e77 cephfs: do not export internal CloneStatus type
getCloneInfo() does not need to return a full CloneStatus struct that
only has one member. Instead, it can just return the value of the single
member, so the JSON type/struct does not need to be exposed.

This makes the API for getCloneInfo() a little simpler, so it can be
replaced by a go-ceph implementation later on.

As the function does not return any of the unused attributes anymore, it
is renamed to getCloneStatu() as well.

5fba89f783 cleanup: use libopenstorage/secrets for Vault access
Instead of the hand-rolled Vault usage, use the libopenstorage/secrets
package that provides a nice API. The support for Vault becomes much
simpler and maintainable that way.

68bd44beba rbd: add new controller to regenerate omap data
In the case of Disaster Recovery failover, the
user expected to create the static PVC's. We have
planned not to go with the PVC name and namespace
for many reasons (as in kubernetes it's planned to
support PVC transfer to a new namespace with a
different name and with new features coming in
like data populator etc). For now, we are
planning to go with static PVC's to support
async mirroring.

During Async mirroring only the RBD images are
mirrored to the secondary site, and when the
user creates the static PVC's on the failover
we need to regenerate the omap data. The
volumeHandler in PV spec is an encoded string
which contains clusterID and poolID and image UUID,
The clusterID and poolID won't remain same on both
the clusters, for that cephcsi need to generate the
new volume handler and its to create a mapping
between new volume handler and old volume handler
with that whenever cephcsi gets csi requests it
check if the mapping exists it will pull the new
volume handler and continues other operations.

The new controller watches for the PVs created,
It checks if the omap exists if it doesn't it
will regenerate the entire omap data.

8d3a44d0c4 rbd: add minsnapshotsonimage flag
An rbd image can have a maximum number of
snapshots defined by maxsnapshotsonimage
On the limit is reached the cephcsi will
start flattening the older snapshots and
returns the ABORT error message, The Request
comes after this as to wait till all the
images are flattened (this will increase the
PVC creation time.  Instead of waiting till
the maximum snapshots on an RBD image, we can
have a soft limit, once the limit reached
cephcsi will start flattening the task to
break the chain. With this PVC  creation time
will only be affected when the hard limit
(minsnapshotsonimage) reached.

565038fdfd cephfs: ignore quota when SubVolumeInfo() returns Infinite
There is a type-check on BytesQuota after calling SubVolumeInfo() to see
if the value is supported. In case no quota is configured, the value
Infinite is returned. This can not be converted to an int64, so the
original code returned an error.

It seems that attaching/mounting sometimes fails with the following
error:

    FailedMount: MountVolume.MountDevice failed for volume "pvc-0e8fdd18-873b-4420-bd27-fa6c02a49496" : rpc error: code = Internal desc = subvolume csi-vol-0d68d71a-1f5f-11eb-96d2-0242ac110012 has unsupported quota: infinite

By ignoring the quota of Infinite, and not setting a quota in the
Subvolume object, this problem should not happen again.

8a41cd03a5 journal: fix reading omaps from objects with large key counts
The implementation of getOMapValues assumed that the number of key-value
pairs assigned to the object would be close to the number of keys
being requested. When the number of keys on the object exceeded the
"listExcess" value the function would fail to read additional keys
even if they existed in the omap.
This change sets a large fixed "chunk size" value and keeps reading
key-value pairs as long as the callback gets called and increments
the numKeys counter.
