The new filesystems - var, root and log - are not able to be modified
from the GUI, because the form does not show these filesystems.
This fix adds the new filesystems so they can be modified.
Closes-Bug: 2008810
Test Plan:
PASS: Modify the new filesystems from the GUI. If the size is
decreased, the appropriate error message will be displayed.
PASS: Modify the other filesystems from the GUI. If the size is
decreased, the appropriate error message will be displayed.
