[Feature/extensions] Fish out Create Detector and remove everything else for extensions.

[saratvemulapalli]

Description

Commenting out code for all features of AD except create detector.

I've manually tested and create detector still works.

Manual Test

1. Create Index

curl -XPUT localhost:9200/server_log --data '{
"mappings" : {
    "_default_":{
        "_timestamp" : {
            "enabled" : true,
            "store" : true
        }
    }
  }
}' -H "Content-Type:application/json"

2. Ingest a doc

curl -XPUT "localhost:9200/server_log/_doc/1?pretty" --data '{"date": "2015-01-01"}' -H "Content-Type:application/json"
{
  "_index" : "server_log",
  "_id" : "1",
  "_version" : 1,
  "result" : "created",
  "_shards" : {
    "total" : 2,
    "successful" : 1,
    "failed" : 0
  },
  "_seq_no" : 0,
  "_primary_term" : 1
}

3. Create Detector

curl -XPOST "localhost:9200/_plugins/_anomaly_detection/detectors?pretty" -H "Content-Type:application/json" --data '{
"name":"test-detector", "time_field":"date", "indices": [ "server_log*" ]
}'
{
  "_id" : "XinDW4IBUCK3JmVb3oQ0",
  "_version" : 1,
  "_seq_no" : 0,
  "anomaly_detector" : {
    "name" : "test-detector",
    "description" : "",
    "time_field" : "date",
    "indices" : [
      "server_log*"
    ],
    "filter_query" : {
      "match_all" : {
        "boost" : 1.0
      }
    },
    "detection_interval" : {
      "period" : {
        "interval" : 10,
        "unit" : "Minutes"
      }
    },
    "window_delay" : {
      "period" : {
        "interval" : 0,
        "unit" : "Seconds"
      }
    },
    "shingle_size" : 8,
    "schema_version" : 0,
    "feature_attributes" : [ ],
    "last_update_time" : 1659396939315,
    "detector_type" : "SINGLE_ENTITY"
  },
  "_primary_term" : 1
}

Note I'll mark the PR in draft state to comment out the tests. Obviously a lot of tests would fail :)
Everything works!!

LGTM although it's hard to review a negative diff. Makes me wonder if we shouldn't just start with a fresh repo and bring things over that we want to keep.

Looking for one more pair of eyes.
@owaiskazi19 @joshpalis @ryanbogan if you guys have some bandwidth.

+1 to this. @saratvemulapalli WDYT?

[owaiskazi19]

Should we merge #619 before this?

[saratvemulapalli]

@dbwiddis @owaiskazi19 The problem maintain a fresh piece of code is that we have to keep understanding the diff between main and feature/extensions.
Its going to be hard to track them, commented code will have everything in place and merging will be easy down the line.

I would propose keeping this branch with all commented code and when we start integrating the SDK we can pull the fresh pieces of code. What do you guys think?

Makes sense. Thanks for showing the big picture here.

Thats a good point.
Sure let me review those changes. I'll wait until the PR is merged.
