Expose the mappings of a given index or index/type

[rgl]

It would be nice to get the mappings of a given index or index/type pair by doing a GET.

For example, I would like to have something like:

• "GET /logs/_mapping" to get all the mappings defined in the "logs" index.
• "GET /logs/log/_mapping" to get the mappings of the "logs/log" type.
• "GET /_mapping" to get all the mappings.

Note that this is currently possible by doing a GET of "/_cluster/state" but that also obtains a bunch of non related information, and one still has to parse the json (the mappings come in a json encoded string).

pushed a change to the cluster state to return native json mapping (in an array of mappings) when possible. Its an oversight on my part, I had to enhance some aspects to be able to do it, but its already there, so its a simple fix.

It would be practical to have an options to get mappings as a part of index REST API as well. (i.e. it would be possible to get more info about index via one REST request, no need to do two or more requests).

Expose the mappings of a given index or index/type, closed by 7b145fd. Added the ability to filter returned data from the cluster state API, and use it to expose REST GET endpoint for "/_mapping", "/{index}/_mapping", "/{index}/{type}/_mapping" ({index} can also be "_all").
