Tests not getting updated when tslint.json is updated

From @Turbo87 in #12

one issue I noticed though is that when I change the tslint.json file the tests are apparently not updated, but that seems to be a different issue and unrelated to fixing the extends feature.

In general, changing config will require a restart of the build (this is true of package.json, .eslintrc.js, ember-cli-build.js, etc).

@rwjblue that might be the current state, but is there no way to fix that?

[rwjblue]

It is currently not possible to watch things in the root of the project because changes in tmp would also be watched and cause infinite rebuild loop. Using watchman helps a little bit, because it suppresses the rebuild triggered by ./tmp changes (since we have a config file that ignores tmp and dust), but watchman isn't required (or well supported for some of our platforms).

tldr; upgrading to broccoli@1 unblocks things like this (conceptually), but it's still pretty difficult to reason about

[rwjblue]

It's probably possible to do a one off solution for this particular case (basically forcing a content comparison of the tslint.json for every build), but I wouldn't trigger a rebuild upon changing the lint config (it would only allow a subsequent watched file change to pull in the new config).
