linkquality: added link_quality to add delay, loss and rate limit to link

This adds the ability to assign delay and loss to links.

4 new object types are introduced:
- LinkQuality
- Delay
- Loss
- Rate

All attributes are read-only, one attribute link_quality is added to the
ShimEthDIF with a callback to the LinkQualityManager which will automatically
apply a new link_quality profile when this attribute is written.
