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.

Ensure that any new configuration files are written to disk
prior to performing the package upgrade between OpenStack
releases; this ensures that the new versions of the daemons
start with the correct configuration from initial start on
package post installation configuration.

The nova-cloud-controller presents a restart_nonce key on the
quantum-network-service relation once db migration has been
completed and the nova-conductor service is able to respond to
RPC calls.
Restart the nova-api-metadata when this data changes to ensure
a running service post deployment.

Includes dropping support for quantum, nvp plugin (renamed
nsx long ago) and generally refactoring the unit tests
around no longer having to deal with neutron and quantum in
the same codebase.
Drop support for database connections - these are no longer
required as all DB access is now via RPC to nova-conductor
or neutron-server.
Roll-up configuration file templates < icehouse, remove any
that are no longer required.
Refactor basic_deployment a bit as it was using the shared-db
relation to retrieve the n-gateway units private-address.
