As part of daemon init, network and ipam drivers are passed a
pluginstore object that implements the plugin/getter interface. Use this
interface methods in libnetwork to interact with network plugins. This
interface provides the new and improved pluginv2 functionality and falls
back to pluginv1 (legacy) if necessary.

If a remote plugin returns an empty string in response to RequestAddress(),
the internal helper will return nil which will crash libnetwork in several
places.
Treat an empty string as a new error ipamapi.ErrNoIPReturned.

- This brings the remote ipam driver in pair with the local one.
As of now remote driver package is assuming a valid address in CIDR
form is always present in a nil error AddressRequestResponse,
which is no longer true as community has requested to remove this
limitation.
- We are ok to remove it until we can provide a null ipam driver
option in future releases.
