Rest High Level client putMapping operation doesn't respect IndicesOptions.lenientExpandOpen()

[Evgueni-Gordienko]

Elasticsearch version (bin/elasticsearch --version): the latest

JVM version (java -version): 1.8

OS version (uname -a if on a Unix-like system): Mas OS

Description of the problem including expected versus actual behavior:
When performing putMapping operation via Rest High Level Client and setting indices option to lenientExpandOpen an ElasticsearchStatusException is thrown in case when no indices were found. I expect no error to be returned.

Steps to reproduce:
Just perform something like this:

esRestClient.indices()
                        .putMapping(new PutMappingRequest(indices)
                                            .indicesOptions(IndicesOptions.lenientExpandOpen())
                                            .type(type)
                                            .source(mappings),
                                    RequestOptions.DEFAULT);

The root cause is in org.elasticsearch.client.IndicesRequestConverters, line 134.
For some reason, for the putMapping method there is no line like the following:
parameters.withIndicesOptions(putMappingRequest.indicesOptions()); which is present in many other methods of the class.

Because of that the resulting URL doesn't include the following parameters:
?ignore_unavailable=true,allow_no_indices=true,expand_wildcards_open=true,expand_wildcards_closed=false

And hence, I am getting back index_not_found_exception.

@Evgueni-Gordienko thanks for raising this, good catch and spot-on analysis. I opened a PR to fix this in the next 7.7 patch version.

@cbuescher sure, thanks for scheduling the fix.
