(#4914) Update property blocks

The action for a specific ensure state depends on the actual state so we
cannot use the default behaviour. The following transitions are now
supported (with ghost = mounted but not present in fstab):

• 4 Is-states : absent, mounted, unmounted, ghost
• 4 Should-states: absent, mounted, present, unmounted

• from ghost to present -> create
• from absent to present -> create
• from ghost to unmounted -> create, umount
• from mounted to unmounted -> umount
• from absent to unmounted -> create
• from ghost to absent -> umount (may fail on certain OS)
• from mounted to absent -> umount, destroy
• from unmounted to absent -> destroy
• from ghost to mounted -> create
• from absent to mounted -> create, mount
• from unmounted to mounted -> mount

Every other combination is treatet insync
