Bug Description

reproduce steps:
1. nova-manage network create private 4.4.4.0/24
2. nova-manage network delete --uuid='xxx'
3. nova-manage network create private 4.4.4.0/24
4. nova boot

the instance will have no fixed ip assigned right because of the deleted fixed address:
nova/db/api.py:
def fixed_ip_update(context, address, values):
    session = get_session()
    with session.begin():
        fixed_ip_ref = fixed_ip_get_by_address(context,
                                               address,
                                               session=session)
        fixed_ip_ref.update(values)
        fixed_ip_ref.save(session=session)

def fixed_ip_get_by_address(context, address, session=None):
    result = model_query(context, models.FixedIp, session=session,
                         read_deleted="yes").\
                     filter_by(address=address).\
                     first()
    if not result:
        raise exception.FixedIpNotFoundForAddress(address=address)

    # NOTE(sirp): shouldn't we just use project_only here to restrict the
    # results?
    if is_user_context(context) and result['instance_id'] is not None:
        instance = instance_get(context, result['instance_id'], session)
        authorize_project_context(context, instance.project_id)

return result

the deleted remarked ip will always be updated instead of the right twin.

hmm, looks like we need to change _fixed_ip_get_by_address to take read_deleted from context and pass it in when we need it.

fixed_ip_get_by_address read_deleted from context

    Fixes bug 996482. by default fixed_ip_get_by_address
    always sets read_deleted='yes'. Changed it to accept
    read_deleted value from context.
    updated .mailmap to rewrite my old email to new email

Please find the attached test log from the Ubuntu Server Team's CI infrastructure. As part of the verification process for this bug, Nova has been deployed and configured across multiple nodes using precise-proposed as an installation source. After successful bring-up and configuration of the cluster, a number of exercises and smoke tests have be invoked to ensure the updated package did not introduce any regressions. A number of test iterations were carried out to catch any possible transient errors.

Please Note the list of installed packages at the top and bottom of the report.
