When the provisioning test gets stuck, the log fills up with messages
about waiting for a certain pod to run. Now the pod names are
pvc-[volume-tester|snapshot]-[writer|reader] plus the random
number appended by Kubernetes. This makes it easier to see where the
test is stuck.
There is no need to check for empty strings, we can also directly
initialize structs with the value. The end result is the same when the
value is empty (empty string in the struct).
This addresses the two remaining change requests from
https://github.com/kubernetes/kubernetes/pull/69036:
- replace "csi-hostpath-v0" name check with capability
check (cleaner that way)
- add feature tag to "should create snapshot with defaults" because
that is an alpha feature

Even if snapshots are supported by the driver interface, the driver or
suite might still want to skip a particular test, so those checks
still need to be executed.
systemd is the recommended driver as per the setup of running
the kubelet using systemd as the init system. Add a preflight
check that throws a warning if this isn't the case.
Currently JoinConfigFileAndDefaultsToInternalConfig is doing a couple of
different things depending on its parameters. It:
- loads a versioned JoinConfiguration from an YAML file.
- returns defaulted JoinConfiguration allowing for some overrides.
In order to make code more manageable, the following steps are taken:
- Introduce LoadJoinConfigurationFromFile, which loads a versioned
JoinConfiguration from an YAML file, defaults it (both dynamically and
statically), converts it to internal JoinConfiguration and validates it.
- Introduce DefaultedJoinConfiguration, which returns defaulted (both
dynamically and statically) and verified internal JoinConfiguration.
The possibility of overwriting defaults via versioned JoinConfiguration is
retained.
- Re-implement JoinConfigFileAndDefaultsToInternalConfig to use
LoadJoinConfigurationFromFile and DefaultedJoinConfiguration.
- Replace some calls to JoinConfigFileAndDefaultsToInternalConfig with calls to
either LoadJoinConfigurationFromFile or DefaultedJoinConfiguration where
appropriate.
- Rename JoinConfigFileAndDefaultsToInternalConfig to the more appropriate name
LoadOrDefaultJoinConfiguration.
