…earch We currently use the same internal request when we need to free the search context after a search and a scroll. The two original requests though diverged after elastic#6933 as `SearchRequest` implements `IndicesRequest` while `SearchScrollRequest` and `ClearScrollRequest` don't. That said, with elastic#7319 we made `SearchFreeContextRequest` implement `IndicesRequest` by making it hold the original indices taken from the original request, which are null if the free context was originated by a scroll or by a clear scroll call, and that is why original indices are optional there. This commit introduces a separate free context request and transport action for scroll, which doesn't hold original indices. The new action is only used against nodes that expose it, the previous action name will be used for nodes older than 1.4.0.Beta1. As a result, in 1.4 we have a new `indices:data/read/search[free_context/scroll]` action that is equivalent to the previous `indices:data/read/search[free_context]` whose request implements now `IndicesRequest` and holds the original indices coming from the original request. The original indices in the latter requests can only be null during a rolling upgrade (already existing version checks make sure that serialization is bw compatible), when some nodes are still < 1.4.

Similar to elastic#7856 but relates to the fetch shard level requests. We currently use the same internal request when we need to fetch within search and scroll. The two original requests though diverged after elastic#6933 as SearchRequest implements IndicesRequest while SearchScrollRequest doesn't. That said, with elastic#7319 we made `FetchSearchRequest` implement IndicesRequest by making it hold the original indices taken from the original request, which are null if the fetch was originated by a search scroll, and that is why original indices are optional there. This commit introduces a separate fetch request and transport action for scroll, which doesn't hold original indices. The new action is only used against nodes that expose it, the previous action name will be used for nodes older than 1.4.0.Beta1. As a result, in 1.4 we have a new `indices:data/read/search[phase/fetch/id/scroll]` action that is equivalent to the previous `indices:data/read/search[phase/fetch/id]` whose request implements now IndicesRequest and holds the original indices coming from the original request. The original indices in the latter request can only be null during a rolling upgrade (already existing version checks make sure that serialization is bw compatible), when some nodes are still < 1.4.
