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.
Adds the test "should be able to pull image from docker hub [WindowsOnly]",
which will pull a Windows busybox image from dockerhub. Since it is busybox,
the same command will also work for this image.
The busybox image is currently used in other E2E tests, so the image should
already be prepulled on the nodes. Additionally, the image has a manifest list
for Windows Server 1803 and Windows Server 2019, and future versions will be
added to it.
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.
