[LHN Mismatch] Add SetCollection to Onyx

[puneetlath]

We are going to be changing the behavior of OpenApp/ReconnectApp when it does a full reconnect to replace the full reports list that the client has stored instead of merging with it. In order to do that, we need to be able to send a list of report objects to the client and have Onyx.set be called for each of those reports. And have any reports that weren't included get cleared. In order to support this, let's add SetCollection to Onyx.

@puneetlath should the API for setCollection be something like this?

Onyx.setCollection(ONYXKEYS.COLLECTION.REPORT, [
     { [`${ONYXKEYS.COLLECTION.REPORT}1`]: report1 },
     { [`${ONYXKEYS.COLLECTION.REPORT}2`]: report2 }
 ]);

[puneetlath]

I think the API for it should look basically exactly like mergeCollection. Which I believe would mean it looks like this:

Onyx.setCollection(ONYXKEYS.COLLECTION.REPORT, {
    [`${ONYXKEYS.COLLECTION.REPORT}${report1.reportID}`]: report1,
    [`${ONYXKEYS.COLLECTION.REPORT}${report2.reportID}`]: report2,
    [`${ONYXKEYS.COLLECTION.REPORT}${report3.reportID}`]: report3,
});

Unless there's some reason you think it should be different.

How's this going @zirgulis?
