The generated ceph.conf does not need readable by the group, there is
only one (system) user consuming the configurations file.
This addresses the following gosec warning:
[/go/src/github.com/ceph/ceph-csi/internal/util/cephconf.go:52] - G306 (CWE-): Expect WriteFile permissions to be 0600 or less (Confidence: HIGH, Severity: MEDIUM)

For building a arm64 container image on amd64, it is needed to configure
the system specifically for that. In order to prevent including a amd64
executable in a arm64 image, a check has been added.
When running an arm64 executable on a amd64 system, an error should
occur when cross architecture containers are not supported. This can be
triggered when running `make image-cephcsi GO_ARCH=arm64` on a amd64
system.

This prevents some clutter while running 'make' commands on an
environment where 'go' is not installed. There is no requirement on 'go'
in the case containers are used for building and testing.

With the current code base, the subvolumegroup will
be created once, and even for a different cluster,
subvolumegroup creation is not allowed again.
Added support multiple subvolumegroups creation by
validating one subvolumegroup creation per cluster.

The previous function used to remove omap keys apparently did not
return errors when removing omap keys from a missing omap (oid).
Mimic that behavior when using the api.

Signed-off-by: John Mulligan <jmulligan@redhat.com>
Taking this appraoch means that any function that must get more than one
key's value from the same oid can be more efficient by calling out to
ceph only once.
To be cautious and avoid missing things we always request ceph return
more keys than we actually expect to be set on the oid. If there are
unexpected keys there, we will not miss the keys we want if we first hit
an unexpected key if we were to limit ourselves to iterating only over
the number of keys we're expecting to be on the object.

go-ceph v0.3 adds constants for ImageFeature values and their names.
Instead of hardcoding "layering" in several places, use the constant
given by librbd.
The rbdVolume.ImageFeatures does not seem to be used anywhere after the
conversion. Stashing the image metadata does include the ImageFeatures
as these are retrieved when getting the image information. It is safe to
drop ImageFeatures altogether and only use the imageFeatureSet instead.

It seems that convering the release component from the unix.Utsrelease
type leaves some trailing "\x00" characters.
While splitting the string to compare kernel versions, these additional
characters might prevent converting the string to an int. Strip the
additional characters before returning the string.
Note:
"\x00" characters are not visible when printing to a file or screen.
They can be seen in hex-editors, or sending the output through 'xxd'.
