Don't initialize neutronv2 state at module import
Don't initialize neutronv2 state at module import

Currently, neutronv2.API defines conductor_api when the module is
imported. This could easily happen before any configuration files are
parsed so e.g. use_local may not be applied.

In the case of oslo.messaging, I was seeing this cause problems bcause
it was happening before oslo.messaging transport was initialized.
