[DOCS] Remove heading offsets for REST APIs (#44568) Several files in the REST APIs nav section are included using :leveloffset: tags. This increments headings (h2 -> h3, h3 -> h4, etc.) in those files and removes the :leveloffset: tags. Other supporting changes: * Alphabetizes top-level REST API nav items. * Change 'indices APIs' heading to 'index APIs.' * Changes 'Snapshot lifecycle management' heading to sentence case.

[DOCS] Move Elasticsearch APIs to REST APIs section. (#44238) (#44372) Moves the following API sections under the REST APIs navigations: - API Conventions - Document APIs - Search APIs - Index APIs (previously named Indices APIs) - cat APIs - Cluster APIs Other supporting changes: - Removes the previous index APIs page under REST APIs. Adds a redirect for the removed page. - Removes several [partintro] macros so the docs build correctly. - Changes anchors for pages that become sections of a parent page. - Adds several redirects for existing pages that become sections of a parent page. This commit re-applies changes from #44238. Changes from that PR were reverted due to broken links in several repos. This commit adds redirects for those broken links.

Index APIs are used to manage individual indices,
Remove warmers and the warmer API. Warmers are now barely useful and will be removed in 3.0. Note that this only removes the warmer API and query-based warmers. We still have warmers internally for eg. global ordinals. Close #15607

Indices API: Added GET Index API Returns information about settings, aliases, warmers, and mappings. Basically returns the IndexMetadata. This new endpoint replaces the /{index}/_alias|_aliases|_mapping|_mappings|_settings|_warmer|_warmers and /_alias|_aliases|_mapping|_mappings|_settings|_warmer|_warmers endpoints whilst maintaining the same response formats. The only exception to this is on the /_alias|_aliases|_warmer|_warmers endpoint which will now return a section for 'aliases' or 'warmers' even if no aliases or warmers exist. This backwards compatibility change is documented in the reference docs. Closes #4069

Add primitive to shrink an index into a single shard (#18270) This adds a low level primitive operations to shrink an existing index into a new index with a single shard. This primitive expects all shards of the source index to allocated on a single node. Once the target index is initializing on the shrink node it takes a snapshot of the source index shards and copies all files into the target indices data folder. An [optimization](https://issues.apache.org/jira/browse/LUCENE-7300) coming in Lucene 6.1 will also allow for optional constant time copy if hard-links are supported by the filesystem. All mappings are merged into the new indexes metadata once the snapshots have been taken on the merge node. To shrink an existing index all shards must be moved to a single node (one instance of each shard) and the index must be read-only: ```BASH $ curl -XPUT 'http://localhost:9200/logs/_settings' -d '{ "settings" : { "index.routing.allocation.require._name" : "shrink_node_name", "index.blocks.write" : true } } ``` once all shards are started on the shrink node. the new index can be created via: ```BASH $ curl -XPUT 'http://localhost:9200/logs/_shrink/logs_single_shard' -d '{ "settings" : { "index.codec" : "best_compression", "index.number_of_replicas" : 1 } }' ``` This API will perform all needed check before the new index is created and selects the shrink node based on the allocation of the source index. This call returns immediately, to monitor shrink progress the recovery API should be used since all copy operations are reflected in the recovery API with byte copy progress etc. The shrink operation does not modify the source index, if a shrink operation should be canceled or if the shrink failed, the target index can simply be deleted and all resources are released.

Add ability to split shards (#26931) This change adds a new `_split` API that allows to split indices into a new index with a power of two more shards that the source index. This API works alongside the `_shrink` API but doesn't require any shard relocation before indices can be split. The split operation is conceptually an inverse `_shrink` operation since we initialize the index with a _syntetic_ number of routing shards that are used for the consistent hashing at index time. Compared to indices created with earlier versions this might produce slightly different shard distributions but has no impact on the per-index backwards compatibility. For now, the user is required to prepare an index to be splittable by setting the `index.number_of_routing_shards` at index creation time. The setting allows the user to prepare the index to be splittable in factors of `index.number_of_routing_shards` ie. if the index is created with `index.number_of_routing_shards: 16` and `index.number_of_shards: 2` it can be split into `4, 8, 16` shards. This is an intermediate step until we can make this the default. This also allows us to safely backport this change to 6.x. The `_split` operation is implemented internally as a DeleteByQuery on the lucene level that is executed while the primary shards execute their initial recovery. Subsequent merges that are triggered due to this operation will not be executed immediately. All merges will be deferred unti the shards are started and will then be throttled accordingly. This change is intended for the 6.1 feature release but will not support pre-6.1 indices to be split unless these indices have been shrunk before. In that case these indices can be split backwards into their original number of shards.

Add Clone Index API (#44267) Adds an API to clone an index. This is similar to the index split and shrink APIs, just with the difference that the number of primary shards is kept the same. In case where the filesystem provides hard-linking capabilities, this is a very cheap operation. Indexing cloning can be done by running `POST my_source_index/_clone/my_target_index` and it supports the same options as the split and shrink APIs. Closes #44128

Add a GetFieldMapping API This new API allows to get the mapping for a specific set of fields rather than get the whole index mapping and traverse it. The fields to be retrieved can be specified by their full path, index name and field name and will be resolved in this order. In case multiple field match, the first one will be returned. Since we are now generating the output (rather then fall back to the stored mapping), you can specify `include_defaults`=true on the request to have default values returned. Closes #3941
