20d336fca3 Add support to use ceph manager rbd command to delete an image
Image deletion takes time proportional to the size of the
image. Hence, ceph manager is enhanced to support async
deletion of an image, or rather passing the task of
deleting an image to the ceph manager.

This commit leverages the ceph manager enhancement in the CSI code.

NOTE: This is tested against a ceph cluster that is running
Ceph master version of the code. Once other releases
catch up in terms of the feature, the optimization would be
available to the CSI driver as well.

31648c8feb provisioners: add reconfiguring of PID limit
The container runtime CRI-O limits the number of PIDs to 1024 by
default. When many PVCs are requested at the same time, it is possible
for the provisioner to start too many threads (or go routines) and
executing 'rbd' commands can start to fail. In case a go routine can not
get started, the process panics.

The PID limit can be changed by passing an argument to kubelet, but this
will affect all pids running on a host. Changing the parameters to
kubelet is also not a very elegant solution.

Instead, the provisioner pod can change the configuration itself. The
pod is running in privileged mode and can write to /sys/fs/cgroup where
the limit is configured.

With this change, the limit is configured to 'max', just as if there is
no limit at all. The logs of the csi-rbdplugin in the provisioner pod
will reflect the change it makes when starting the service:

    $ oc -n rook-ceph logs -c csi-rbdplugin csi-rbdplugin-provisioner-0
    ..
    I0726 13:59:19.737678       1 cephcsi.go:127] Initial PID limit is set to 1024
    I0726 13:59:19.737746       1 cephcsi.go:136] Reconfigured PID limit to -1 (max)
    ..

It is possible to pass a different limit on the commandline of the
cephcsi executable. The following flag has been added:

    --pidlimit=<int>       the PID limit to configure through cgroups

This accepts special values -1 (max) and 0 (default, do not
reconfigure). Other integers will be the limit that gets configured in
cgroups.

885ec7049d Update Unstage transaction to undo steps done in Stage
In unstage we now adhere to the transaction (or order of steps)
done in Stage. To enable this we stash the image meta data
into a local file on the staging path for use with unstage
request.

This helps in unmapping a stale map, in case the mount or
other steps in the transaction are complete.

925bda2881 Move mounting staging instance to a sub-path within staging path
This commit moves the mounting of a block volumes and filesystems
to a sub-file (already the case) or a sub-dir within the staging
path.

This enables using the staging path to store any additional data
regarding the mount. For example, this will be extended in the
future to store the fsid of the cluster, and maybe the pool name
to map unmap requests to the right image.

Also, this fixes the noted hack in the code, to determine in a
common manner if there is a mount on the passed in staging path.

b812ec26df e2e: do not fail deleting resources when "resource not found"
Sometimes the tests fail cleaning up due unavailable resources that are
listed in the .yaml files. Deleting the missing resources returns
"resource not found". By passing --ignore-not-found to kubectl, this
problem should not happen anymore (and possibly makes it more obvious
where tests do go wrong).

02bcb5f16a Enable leader election in v1.14+
Use Deployment with leader election instead of StatefulSet

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
5 minutes for StatefulSet to start a new replica.

bd204d7d45 Use --keyfile option to pass keys to all Ceph CLIs
Every Ceph CLI that is invoked at present passes the key via the
--key option, and hence is exposed to key being displayed on
the host using a ps command or such means.

This commit addresses this issue by stashing the key in a tmp
file, which is again created on a tmpfs (or empty dir backed by
memory). Further using such tmp files as arguments to the --keyfile
option for every CLI that is invoked.

This prevents the key from being visible as part of the argument list
of the invoked program on the system.
