Put Pipeline APIedit

The put pipeline API adds pipelines and updates existing pipelines in the cluster.

PUT _ingest/pipeline/my-pipeline-id
{
  "description" : "describe pipeline",
  "processors" : [
    {
      "set" : {
        "field": "foo",
        "value": "bar"
      }
    }
  ]
}

The put pipeline API also instructs all ingest nodes to reload their in-memory representation of pipelines, so that pipeline changes take effect immediately.
