scopes not updated as often as expected

[Jamie Strandboge]

When using the weather channel scope, I find it doesn't update when I expect. Eg, someone asked me what the temp was going to be and I said '46'. She responded with "What?!? No way, I heard it was supposed to be in the 70s!". Then I responded "oh, let me swipe down-- yes, there we go, 76". Seems that it should maybe update automatically after screen unlock and/or coming back in from another scope.

Other weather apps seem to be able to do this fine. Perhaps this automatic updating would be something a scope could opt in to?

We do have a (limited) support for automatic updating via "TTL" mechanism in the shell plugin; scopes opt in for it by declaring ttl value (small = 30 seconds, medium = 5 minutes, large = 1 hour) in their config file.

We could use it here, only bit missing is to support it for remote scopes - make them declare it in the json here https://dash.ubuntu.com/smartscopes/v2/remote-scopes and make smart scopes client code parse it and expose in scope metadata (so that shell can use it).
