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.

ddac66d76b util: use context.Context for logging in ExecCommand
All calls to util.ExecCommand() now pass the context.Context. In some
cases this is not possible or needed, and util.ExecCommand() will not
log the command.

This should make debugging easier when command executions fail.

7afaac9c66 rbd: implement rbdVolume.isInUse() with go-ceph
The new rbdVolume.isInUse() method will replace the rbdStatus()
function. This removes one more rbd command execution in the
DeleteVolume path.

649aeb7aaf rbd: Add support for rbd ROX PVC mounting
if the PVC access mode is ReadOnlyMany
or single node readonly, mounting the rbd
device path to the staging path as readonly
to avoid the write operation.

If the PVC acccess mode is readonly, mapping
rbd images as readonly.

323cc0e3bb cleanup: avoid comparing errors directly
Go 1.13 contains support for error wrapping. To support wrapping,
fmt.Errorf now has a %w verb for creating wrapped errors, and three
new functions in the errors package ( errors.Unwrap, errors.Is and
errors.As) simplify unwrapping and inspecting wrapped errors.

With this change, If we currently compare errors using ==, we have to
use errors.Is instead. Example:

if err == io.ErrUnexpectedEOF

becomes

if errors.Is(err, io.ErrUnexpectedEOF)

32839948ef cleanup: move pkg/ to internal/
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.

Closes: #903
