Subject: T7886: add basic cases of reverse interface dependency verification

Add cases for which a config mode script calls verify_interface_exists,
excluding those of dynamic_interface_pattern, to be handled separately.
The dependency verification raises error, resp., gives a warning, when
verify_interface_exists is called with warning_only=False, resp., True.
These are the critical cases that motivated the original design, for if
a removal of an interface is allowed, a subsequent reboot will raise
ConfigError on config load and invalidate the config subtree for that
component.
