In #74138 we noted that index settings aren't copied in a clone. In fact
that's not true, we copy everything except explicitly-excluded ones,
`number_of_replicas` and `auto_expand_replicas`. This fixes the mistake.

Changes:
* Expands the `aliases` parameter for the create index API to better document
supported properties.
* Reuses `aliases` parameter in the following API docs:
* Clone index API
* Shrink index API
* Split index API
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
