Disable pylint interface-not-implemented rule
Disable pylint interface-not-implemented rule

interface-not-implemented pylint check is too strict.
It assumes that if some parent class contains 'interface'
as a class name it expects 'Interface' is implemented.
However, the check seems to expect too much and
it is not compatible with the current neutron implementation.
