916c97b4a8 rbd: copy creds when copying the connection
rbd flatten functions is a CLI call and it expects
the creds as the input and copying of creds is
required when we generate the temp clone image.

43f753760b cleanup: resolve nlreturn linter issues
nlreturn linter requires a new line before return
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.

5c26fbb0d7 util: use ClusterConnection.Copy() for re-using connections
Connections are reference counted, so just assigning the connection to
an other object for re-use is not correct. This can cause connections to
be garbage collected while something else is still using it.

fe62348cfb util: add ClusterConnection.GetFSAdmin()
The go-ceph CephFS Admin API needs a rados.Conn to connect the Admin
interface to the Ceph cluster. As the rados.Conn is internal to the
ClusterConnection type, add GetFSAdmin() to create a new FSAdmin
instance for a specific connection.

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.

de74c36d8c cleanup: address err113 warnings about direct error comparisons
Several places in the code compared errors directly with the go-ceph
sentinel errors.  This change uses the errors.Is() function of go
1.13 instead.  The err113 linter reported this issue as:

err113: do not compare errors directly, use errors.Is() instead

92aae4834e cleanup: use standard Golang errors package
"github.com/pkg/errors" does not offer more functionlity than that we
need from the standard "errors" package. With Golang v1.13 errors can be
wrapped with `fmt.Errorf("... %w", err)`. `errors.Is()` and
`errors.As()` are available as well.

01edaf8a71 move rbdVolume connection details to utils.ClusterConnection
The shared util.ClusterConnection can be used for rbd.rbdVolume and
cephfs.volumeOptions to connect to the Ceph cluster. This will then use
the shared ConnPool, and functions for obtaining connection details will
be the same across cephfs and rbd packages.

The ClusterConnection.Creds credentials are temporarily available until
all the functions have been adapted to use go-ceph and the connection
from the ConnPool.
