### Description

Logstash uses the endpoint  `_logstash/pipeline` to retrieve the pipelines configuration from Central Management.
Logstash permit to use the `*` wildcard operator to specify the pipeline names, so a user is not required to list all the pipelines, but just capture the common not changing part of the name. 
Suppose the user has a pipelines with common prefix (for example `pipeline_proxy_1`..`pipeline_proxy_10`), he could also add `pipeline_11` without restarting Logstash and changing the option `xpack.management.pipeline.id`.

Actually the feature is implemented on Logstash side, retrieving all the pipelines and then filtering out the ones that doesn't match; this is a waste. 
This feature request asks to implement the wildcard operator selector on Elasticsearch side.

The rules for wildcard in pipeline names are:
must begin with a letter or underscore and contain only letters, underscores, dashes, and numbers wildcard character `*` is also acceptable and follows globbing rules.

The regexp is defined [here](https://github.com/elastic/logstash/blob/0887d7609df9ba72a5d0cd003c639b16da198622/x-pack/lib/config_management/bootstrap_check.rb#L17-L19).

We could imagine to use the `_logstash/pipeline/<pipeline_id>` where the pipeline_id is a list of comma-separated id (like it's today) but permitting the pipeline_id to use the wildcard operator.
