This PR changes the fingerprint handling of network interfaces that only
contain link local addresses. The new behavior is to prefer globally
routable addresses and if none are detected, to fall back to link local
addresses if the operator hasn't disallowed it. This gives us pre 0.6
behavior for interfaces with only link local addresses but 0.6+ behavior
for IPv6 interfaces that will always have a link-local address.

This will create a concrete mention of job anti-affminity in the Nomad documentation. The only place we discuss it currently is in a similar sentence on the website itself. I borrowed liberally from that sentence in crafting this line.
This PR enhances the distinct_property constraint such that a limit can
be specified in the RTarget/value parameter. This allows constraints
such as:
```
constraint {
distinct_property = "${meta.rack}"
value = "2"
}
```
This restricts any given rack from running more than 2 allocations from
the task group.

We only mention job anti-affinity on the main webpage. This sentence is borrowed from there with minor tweaks to at least introduce it in the docs corpus
* Update operating a job, upgrade guide
