Subject: [PATCH] TEST-15: allow helper functions to accept other unit types

clear_services() is renamed to clear_units() and now takes a full
unit name including the suffix as an argument.

_clear_service() is renamed to clear_unit() and changed likewise.
create_service() didn't have the same underscore prefix, and I don't think
it's useful or needed for a local function, so it is removed.

No functional change.

(cherry picked from commit 5731e1378ad6256e34f3da33ee993343f025c075)
