and branch statements except when the return is alone
inside a statement group (such as an if statement) to
increase code clarity. This commit addresses such issues.

We have many declarations and invocations..etc
with long lines which are very difficult to follow while doing
code reading. This address the issues in 'internal/cephfs' package to
restrict the line length to 120 chars.

Currently we are relaying on the error output from
the umount command we run on the nodes when mounting
the volume but we are not checking for all the error
message to verify the volume is mounted or not.
This commits uses IsMountPoint function in util
to check the mountpoint.

The CephFS NodeServer should handle the CephFS specific requests. This
is not something that the NodeServer for RBD should handle.

Add the ClusterConnection to the volumeOptions type, so that future use
of go-ceph can connect to the Ceph cluster.
Once a volumeOptions object is not needed anymore, it needs to get
destroyed to free associated resources like the ClusterConnection.

In Go 1.13, the fmt.Errorf function supports a new %w verb.
When this verb is present, the error returned by fmt.Errorf
will have an Unwrap method returning the argument of %w,
which must be an error. In all other ways, %w is identical to %v.

When mounting fails, the node-plugin should give a suggestion to check the
kernel logs so that users can report problems better.
Edited the existing log to include the message in both rbd and cephfs.

The internal/ directory in Go has a special meaning, and indicates that
those packages are not meant for external consumption. Ceph-CSI does
provide public APIs for other projects to consume. There is no plan to
keep the API of the internally used packages stable.
