vty_test: add artificial node levels for better testing

In vty_test, add three levels of parent nodes (level1, level2, level3) with
each having a leaf child (child1, child2, child3).

Use these to enhance the vty_test cfg files and test more diverse situations.

The current VTY code expects a go_parent_cb() to be present, otherwise it will
bump right back to the CONFIG_NODE, which will not work with more than one node
level below the CONFIG_NODE. Hence provide a minimal go_parent_cb().
