Feature: Add Ability to Select a Search Pipeline in Comparison Tool

[nung22]

Description

Gives users the ability to integrate search pipelines into their queries when using Search Relevance. Pipelines are available to select under a new dropdown menu labeled Pipeline. The choices are sorted alphabetically by their name and selecting one is optional. Users are able to compare two different queries using the same or different search pipelines.

Ran these queries in Dev Tools to create the search pipelines shown in the example:

PUT /_search/pipeline/a_pipeline 
{
  "response_processors": [
    {
      "rename_field": {
        "field": "FlightNum",
        "target_field": "NewFlightNum"
      }
    }
  ]
}

PUT /_search/pipeline/b_pipeline 
{
  "request_processors": [
    {
      "filter_query" : {
        "tag" : "tag1",
        "description" : "This processor is going to restrict to documents with OpenSearch Dashboards Airlines",
        "query" : {
          "term": {
            "Carrier": "OpenSearch Dashboards Airlines"
          }
        }
      }
    }
  ]
}

PUT /_search/pipeline/c_pipeline 
{
  "request_processors": [
    {
      "filter_query" : {
        "tag" : "tag2",
        "description" : "This processor is going to restrict to documents with Thunder and Lighting as its Origin Weather",
        "query" : {
          "term": {
            "OriginWeather": "Thunder & Lightning"
          }
        }
      }
    }
  ]
}
