I recommend looking at #429 as an example for updating the specification files in the sdf/ folder and adding tests

Hey @scpeters , some updates:

updating the specification files in the sdf/ folder

I've updated only the 1.7 specification file but I found that in other PRs the specification is updated for several versions.
I didn't find information about which version I should target.

Should I add it to the 1.5 and 1.6 too?

and adding tests

I've added only unit test for the addition of the new attribute.
I realized that there is no integration test involving the sdf file test/sensors.sdf
Should I create the integration test for sensor and test the sensor specification?
EDITED: It is being used at link_dom.cc, I will update it

Thanks, @francocipollone , LGTM!

libSDFormat9 supports the 1.7 spec, so I think adding to that is enough.
