Fix passing keystone token to neutronclient instance

Neutron client expects token to be passed as token= argument, while
neutron-metadata-agent passes auth_token= instead. This effectively makes the
client to authenticate against keystone each time it's instantiated. In
neutron-metadata-agent case, it means 'each time a client sends a metadata
request.'

The issue results in high cpu utilization on keystone side when simultaneously
invoking multiple nova instances with cloud-init.
