Rename config_setting

[pauldraper]

Description of the feature request:

Sorry for the bike shedding, but the naming of build settings, config settings, and constraint settings makes them unnecessarily difficult to grok.

I suggest renaming config_setting to condition.

These are not actually "settings" but in fact "conditions". Compare with //conditions:default.

What underlying problem are you trying to solve with this feature?

The general confusion around the three flavors of Bazel "settings."

Have you found anything relevant by searching the web?
