This is the west manifest file for mainline zephyr.
For a burn-in period, we are going to keep west pointing at master to
avoid deps rolls as we iron out any kinks. We can then set its
revision to a SHA after things settle down.
The projects key is mandatory (if there's only one repository, there
wouldn't be much need for west!) so we'll start things off with the
net-tools repository at its current master SHA.
