The function verify_interface_exists requires a reference to the ambient config_dict rather than creating an instance. As access is required to the 'interfaces' path, provide as attribute of class ConfigDict, so as not to confuse path searches of script-specific config_dict instances. (cherry picked from commit 5f23b72)

Change Summary
The function
verify_interface_existsrequires access to the ambientconfig_dict, rather than its own instantiation usingConfigTreeQuery, in order to get the correct working config representation under configd and at boot. Including the root path 'interfaces' for the syntactical verification test as a config_dict key similar to the case ofwith_pkiwould interfere with script-specific path searches (e.g.interfaces_bonding.py); consequently, the dict of path 'interfaces' is included as an attribute of the classConfigDict.This construction appears redundant in the case of, say,
interfaces_ethernet.py, but is of the right generality to cover all cases.Types of changes
