3f06fedf61 Add unit tests for pkg/util/topology.go file
NOTE: If GetTopologyFromDomainLabels took a k8s client as an
argument, we could use the kubernetes fake client to test this
function in addition. This would though break the layers, exposing
k8s semantics in the code into the higher layers. Hence not
changing the same.

19cc28ddea util/cephcmds: have GetOMapValue() return ErrPoolNotFound
On occasion the e2e tests fail as there is an unexpected error while
deleting an RBD image. The particular tests forcefully removes the pool
where the RBD image is stored. Deleting a volume that has been removed
already (or when its parent pool has been wiped), should succeed.

By catching the error that a pool does not exist (anymore), the
provisioner responds to the DeleteVolume request with succes.

a1de56dbd3 tests: in case 'go test' is run in a container, skip TestGetPIDLimit()
In (standard, non-privileged) container environments the /sys/fs/cgroup
mountpoint is not available. This would cause the tests to fail, as
TestGetPIDLimit() tries to write to the cgroup configuration.

The test will work when run as root on a privileged container or
directly on a host (as Travis CI does).

Setting the CEPH_CSI_RUN_ALL_TESTS environment variable to a non-empty
value will cause the test to be executed.

8dc3600899 rbd: use go-ceph API for creating RBD images
This is the initial step for improving performance during provisioning
of CSI volumes backed by RBD.

While creating a volume, an existing connection to the Ceph cluster is
used from the ConnPool. This should speed up the creation of a batch of
volumes significantly.

for backend image, if image notfound it deletes the
reserved keys in omap.

669dc4536f Reduce encryption KMS configuration SC parameters
* 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)
