Fields for measurement appear in all metric paths that contain measurement

[pkittenis]

With a template like

env.host.measurement.field*

And metrics test.host1.net.eth0 and test.host2.net.eth1

The metrics/find query test.host1.net.* will return both eth0 and eth1 even though eth1 is not a host1 metric.

As the measurement produced by the template is net in this case, net is common to both the host1 and host2 tags and there is no way in influx to query for field keys only for a specific tag value, this is likely a limitation that will remain unless the influx query language makes it possible.
