Method names in api/neutron should be consistent

[Akihiro Motoki]

In api/neutron.py, method names vary across neutron services. These method names should be consistent.

[xxx-update]
<singular>_modify
<singular>_update

[xxx-list]
<plural>_get
<plural>_list
<singular>_list

When looking other projects, it seems <singular>_update and <singular>_list are common.
