[RFE] Introduce /ip-address resource

[Hongbin Lu]

This RFE is created according to the feedback of the neutron driver team meeting [1].

@yamamoto suggested to introduce a new API /ip-address/{ip-address}. This API will determine whether the {ip-address} is fixed and floating and then respond with the relevant data, including the data of the port that this address is/was associated with.

There are two major use cases:

* Provide a unified view for two types of IP address (fixed and floating). This facilitates information lookup by an address of unknown type.
* Provide history of an address (i.e. which VM this address is/was associated with in a specific time).

@Hongbin

So according to you like openstack floating ip show <ip-address> by doing this we can have following information :

1. Can give information according to the fixed and floating Ip.
2. Information about port where it is attached.
3. Attached VM information

Do, you want anything else except these ?
