In test environments the default pool size is set to 1, so there is no
redundancy. This causes recent Ceph versions to complain with
HEALTH_WARN as POOL_NO_REDUNDANCY get set.
By disabling the mon_warn_on_pool_no_redundancy option in ceph.conf, the
warning is not reported and the cluster is marked HEALTHY.

While testing with tehj default 3000 MB RAM in the minikube VM, creating
a encrypted RBD volume fails because 'cryptsetup' gets killed:
[ 766.072585] Out of memory: Kill process 18497 (cryptsetup) score 1182 or sacrifice child
[ 766.072589] Killed process 18497 (cryptsetup) total-vm:863136kB, anon-rss:510336kB, file-rss:10788kB, shmem-rss:0kB

Using 4 GB RAM should prevent this from occuring.

In case there is a minikube executable in the $PATH already, use that
for all commands. If there is none, install_minikube() will place a
newly downloaded executable in /usr/local/bin which will be used by the
full pathname, so that commands as root without /usr/local/bin in the
$PATH will work.

When starting minikube as root with --driver=kvm2, minikube complains
that this is not the right thing to do. However, in the CentOS CI we
really want to run as root, as that makes the scripts simpler.
Add the --force option while starting, so that minikube does not abort
anymore.

The jjb-validate job can not be run in parallel, so it may fail when

In case of problems, leave the following comment in the PR and the job
should restart:

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.

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.

Current versions of the mkfs.xfs binary enable reflink support by
default. This causes problems on systems where the kernel does not
support this feature. When the kernel the feature does not support, but
the filesystem has it enabled, the following error is logged in `dmesg`:
XFS: Superblock has unknown read-only compatible features (0x4) enabled
Introduce a check to see if mkfs.xfs supports the `-m reflink=` option.
In case it does, pass `-m reflink=0` while creating the filesystem.
The check is executed once during the first XFS filesystem creation. The
result of the check is cached until the nodeserver restarts.

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.
