Refactor common.GetBridgeNetDev
...
- Optimize. Use LinkByName instead of iterating over list of available
links. Linux does not support interfaces with the same names.
- Remove unnecessary indirection in utility functions which return
common.NetDev.

* highlight the need for `weave expose` in CNI/k8s
Fixes #2405
* Extend error message
* rearranged the sentences
weave launch <peer hosts> seems a bit orphaned here maybe include the weave connect command as well, since it's being mentioned.

Add AWSVPC setup routines to the attach script
...
When running in the AWSVPC mode, we need to do the following:
- Keep the HW TX offloading on.
- Check that the allocated address belongs to the default subnet,
because only one subnet is allowed and it should be the default one.
If it is not possible to determine whether AWSVPC is on, we ignore
all the steps, because the attachment routines have to work
regardless whether the router is running and the AWSVPC detection
is done by querying the /ipinfo/tracker endpoint served by
the router.

clever about logging.
