- 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)

On systems with SELinux enabled, non-privileged containers
can't access data of privileged containers. Since the socket
is exposed by privileged containers, all sidecars must be
privileged too. This is needed only for containers running
in daemonset as we are using bidirectional mounts in daemonset

currently, we are making use of host path directory
to store the provisioner socket, as this
the socket is not needed by anyone else other than
containers inside the provisioner pod using the
empty directory to store this socket is the best option.

Update CI merge job to build and push Arm64 image to
quay.io/cephcsi/cephcsi:version-arm64.
Add CI PR job running on Travis Arm64 nodes to make sure cephcsi
compiles successfully on Arm64.
No CI test job is availabe for Arm64 now due to below issues
- k8s-csi sidecar images for Arm64 are not available
- Travis Arm64 CI job runs inside unprivileged LXD which blocks
launching minikube test environment

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.
