Watcher: Add support for aliases for watches/triggered watches index (elastic/elasticsearch#3770)
As discussed in #elastic/elasticsearch-migration/79 supporting aliases for watcher allows the migration plugin to work. This adds the relevent checks in the WatchStore and the TriggeredWatchStore that aliases are supported, as the current assumption was always to just load an index. Also, this rarely sets those indices as aliases in all the integration tests, so that this case gets tested. Note: The new WatchStoreUtils.getConcreteIndex() method will be put into core, as this is a useful helper for others. Original commit: elastic/x-pack-elasticsearch@4a98af691d
