9bd10d2698 cephfs: newVolumeOptions() does not need all secrets, only credentials
There is no need to pass all secrets on to newVolumeOptions(), it only
needs the credentials. As the caller of newVolumeOptions() already has
the credentials generated, just pass them along instead of the raw
secrets.

0f108edc7b cephfs: connect to the Ceph Cluster with go-ceph
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.

When passing

36469b87e2 util: make ExecComand return stdout and stderr as string
Most consumers of util.ExecCommand() need to convert the returned []byte
format of stdout and/or stderr to string. By having util.ExecCommand()
return strings instead, the code gets a little simpler.

A few commands return JSON that needs to be parsed. These commands will
be replaced by go-ceph implementations later on. For now, convert the
strings back to []byte when needed.

8393fbe40b util: simplify error handling
The sentinel error code had additional fields in the errors, that are
used nowhere.  This leads to unneccesarily complicated code.  This
change replaces the sentinel errors in utils with standard errors
created with errors.New() and adds a simple JoinErrors() function to
be able to combine sentinel errors from different code tiers.

1e5370a1f3 cephfs: return volume not found error if volume doesnot exists
In some ceph version if the subvolume is not present, the
ceph returns doesnot exists and in some version not found
error message. This commit fixes issue for both error
checks.

By only checking Error ENOENT: for doesnot exist seems good.
even if some error message changes in ceph ceph-csi wont get
any issue.

```bash
sh-4.2# ceph version
ceph version 14.2.10 (b340acf629a010a74d90da5782a2c5fe0b54ac20) nautilus (stable)

sh-4.2# ceph fs subvolume getpath myfs csi-vol-a24a3d97-c7f4-11ea-8cfc-0242ac110012 --group_name csi
Error ENOENT: subvolume 'csi-vol-a24a3d97-c7f4-11ea-8cfc-0242ac110012' does not exist
```

```bash
sh-4.2# ceph version
ceph version 14.2.4 (75f4de193b3ea58512f204623e6c5a16e6c1e1ba) nautilus (stable)

52603d595a journal: split journal types creating a new Connection type
Before, the one CSIJournal type was handling both configuration and
providing methods to make changes to the journal. This created the
temptation to modify the state of the global configuration object to
enact changes through the method calls.

This change creates a new type `journal.Connection` that takes the
monitors and credentials to create a short(er)-lived object to actually
read and make changes on the journal. This also avoid mixing the
arguments needed to connect to the cluster with the arguments needed
for the various journal read & update calls.

78a6de2bd0 journal: remove SetCSIDirectorySuffix to simplify journal creation
The function SetCSIDirectorySuffix was used only one per (long-lived,
gloabl) journal object. It is simpler to construct the journal objects
with this needed parameter:
1. As it is required to function and non-optional AFAICT
2. Removes the temptation to mutate global object
3. Reduces LOC with exact same functionality
4. SetCSIDirectorySuffix would not behave correctly if called a 2nd time
   anyway.

Point 4. means that if you called the function twice to change the
suffix when you previously had "csi.volumes.alice", you'd get
"csi.volumes.alice.bob" instead of "csi.volumes.bob" what one would
expect.
