Geo: Don't flip longitude of envelopes crossing dateline (#34535)
When a envelope that crosses the dateline is specified as a part of
geo_shape query is parsed it shouldn't have its left and right points
flipped.

Fix threshold frequency computation in Suggesters (#34312)
The `term` and `phrase` suggesters have different options to filter candidates
based on their frequencies. The `popular` mode for instance filters candidate
terms that occur in less docs than the original term. However when we compute this threshold
we use the total term frequency of a term instead of the document frequency. This is not inline
with the actual filtering which is always based on the document frequency. This change fixes
this discrepancy and clarifies the meaning of the different frequencies in use in the suggesters.
It also ensures that the threshold doesn't overflow the maximum allowed value (Integer.MAX_VALUE).

Disallow negative query boost (#34486)
This change disallows negative query boosts. Negative scores are not allowed in Lucene 8 so
it is easier to just disallow negative boosts entirely. We should also deprecate negative boosts
in 6x in order to ensure that users are aware when they'll upgrade to ES 7.

Scroll queries asking for rescore are considered invalid (#32918)
This PR changes our behavior from silently ignoring rescore in a scroll query to instead report to the user that such a query is invalid.

Set maxScore for empty TopDocs to Nan rather than 0 (#32938)
We used to set `maxScore` to `0` within `TopDocs` in situations where there is really no score as the size was set to `0` and scores were not even tracked. In such scenarios, `Float.Nan` is more appropriate, which gets converted to `max_score: null` on the REST layer. That's also more consistent with lucene which set `maxScore` to `Float.Nan` when merging empty `TopDocs` (see `TopDocs#merge`).

Make Geo Context Mapping Parsing More Strict (#32821)
Currently, if geo context is represented by something other than
geo_point or an object with lat and lon fields, the parsing of it
as a geo context can result in ignoring the context altogether,
returning confusing errors such as number_format_exception or trying
to parse the number specifying as long-encoded hash code. It would also
fail if the geo_point was stored.

This commit makes the mapping parsing more strict and will fail during
mapping update or index creation if the geo context doesn't point to
a geo_point field.

Limit the number of concurrent requests per node (#31206)
With `max_concurrent_shard_requests` we used to throttle / limit
the number of concurrent shard requests a high level search request
can execute per node. This had several problems since it limited the
number on a global level based on the number of nodes. This change
now throttles the number of concurrent requests per node while still
allowing concurrency across multiple nodes.

Match phrase queries against non-indexed fields should throw an exception (#31060)

Also changes `*Match*QueryBuilderTests` so that it avoids this scenario

Change ScriptException status to 400 (bad request) (#30861)
Currently failures to compile a script usually lead to a ScriptException, which
inherits the 500 INTERNAL_SERVER_ERROR from ElasticsearchException if it does
not contain another root cause. Instead, this should be a 400 Bad Request error.
This PR changes this more generally for script compilation errors by changing 
ScriptException to return 400 (bad request) as status code.

Use geohash cell instead of just a corner in geo_bounding_box (#30698)
Treats geohashes as grid cells instead of just points when the
geohashes are used to specify the edges in the geo_bounding_box
query. For example, if a geohash is used to specify the top_left
corner, the top left corner of the geohash cell will be used as the
corner of the bounding box.

Fail queries with scroll that explicitely set request_cache (#27342)
Queries that create a scroll context cannot use the cache.
They modify the search context during their execution so using the cache
can lead to duplicate result for the next scroll query.

This change fails the entire request if the request_cache option is explictely set
on a query that creates a scroll context (`scroll=1m`) and make sure internally that we never
use the cache for these queries when the option is not explicitely used.
For 6.x a deprecation log will be printed instead of failing the entire request and the request_cache hint
will be ignored (forced to false).
