Some settings may be considered sensitive, such as passwords, and storing them
in the configuration file on disk is not good from a security perspective. This change
allows settings to have a special value, `${prompt::text}` or `${prompt::secret}`, to
indicate that elasticsearch should prompt the user for the actual value on startup.
This only works when started in the foreground. In cases where elasticsearch is started
as a service or in the background, an exception will be thrown.
Closes#10838
Currently, when trying to determine if a location is within one of the configured repository
paths, we compare the root path against a normalized path but the root path is never
normalized so the check may incorrectly fail. This change normalizes the root path and
compares it to the other normalized path.

A `_parent` field can only point to a type that doesn't exist yet.
The validation that checks this relied on have all mappings in the
MapperService. The issue is that this check is performed on the
elected master node and it may not have the IndexService at all
to perform this check. In that case it creates a temporary IndexService and
MapperService to perform mapping validation, but only the mappings
that are part of the put index call are created, not the already existing mappings.
Because of that the `_parent` field validation can't be performed.
By changing the validation to rely on the cluster state's IndexMetaData instead
we can get around the issue with the IndexService/MapperService on the elected
master node. The IndexMetaData always holds the MappingMetaData instances
for all types.
When the dfs phase runs a SearchContext is created on each node that has a shard
for this query. When the query phase (or query and fetch phase) failed that SearchContext
was released only if the query was actually executed on the node. If for example
the query was rejected because the thread pool queue was full then the search context
was not released.
This commit adds a dedicated call for releasing the SearchContext in this case.
In addition, we must set the docIdsToLoad to null in case the fetch phase failed, otherwise
search contexts might not be released in releaseIrrelevantSearchContexts.

Currently all settings that were specified during repository creation are displayed. This commit enables plugins such as cloud-aws to filter out sensitive settings from the repository.
Closes#11265
When using async fetch, we can end up with cluster updates and reroutes based on teh number of shards. While not disastrous we can optimize it, since a single reroute is enough to apply to all the async fetch results that arrived during that time.
* Cut the `has_child` and `has_parent` queries over to use Lucene's query time global ordinal join. The main benefit of this change is that parent/child queries can now efficiently execute if parent/child queries are wrapped in a bigger boolean query. If the rest of the query only hit a few documents both has_child and has_parent queries don't need to evaluate all parent or child documents any more.
* Cut the `_parent` field over to use doc values. This significantly reduces the on heap memory footprint of parent/child, because the parent id values are never loaded into memory.
Breaking changes:
* The `type` option on the `_parent` field can only point to a parent type that doesn't exist yet, so this means that an existing type/mapping can't become a parent type any longer.
* The `has_child` and `has_parent` queries can no longer be use in alias filters.
All these changes, improvements and breaks in compatibility only apply for indices created with ES version 2.0 or higher. For indices creates with ES <= 2.0 the older implementation is used.
It is highly recommended to re-index all your indices with parent and child documents to benefit from all the improvements that come with this refactoring. The easiest way to achieve this is by using the scan and bulk apis using a simple script.
