James Page b63f8687f9 Update for Python 3 execution
Refactor codebase and unit tests to default to execution
under Python 3.

Drop install shim as Python 3 is always present >= trusty.

Drop legacy dhcp and network reassignment code from charm as
a) this relies on a py3 neutronclient (not supported on older
releases) and b) this function was superceeded by the ha-legacy-mode
and then neutron router and network HA built in functionality.

Use charmhelper provided get_host_ip as this superceeds the in
charm version of this function.
