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.

- Remove from contract predefined errors which are no longer
valid (ex. ErrInvalidIpamService, ErrInvalidIpamConfigService)
- Do not use network driver error for ipam load failure in controller.go
- Bitseq to expose two well-known errors (no more bit available, bit is already set)
- Default ipam to report proper well-known error on RequestAddress()
based on bitseq returned error
- Default ipam errors to comply with types error interface
