==== Suggest stats metrics deprecated

The suggest stats were previously folded into the search on the indices stats
API. As such, the `suggest` metric on the indices stats API has been a synonym
for the `search` metric. In 6.3.0, the `suggest` metric is deprecated in favor
of using `search`.

Similarly, the `suggest` index metric on the `indices` metric on the nodes stats
API has provided a response containing only an empty object since 5.0.0. In
6.3.0 this metric has been deprecated.

=== Packaging changes

Starting with version 6.3, all of the {xpack} features ship with the default 
distribution of {es}. You no longer need to install {xpack} separately. <commit_msg>[DOCS] Adds missing link in breaking changes<commit_after>[[breaking-changes-6.3]]
