[Elastic Agent] Enable TSDB by default

[constanca-m]

What does this PR do?

Enable TSDB by default for all metrics data streams, except for:

• Endpoint security metrics: it never receives any data.
• Filebeat input metrics: the migration is failing with

  Error: error running package asset tests: could not complete test run: can't install the package: can't install the package: could not install package; API status code = 500; response body = {"statusCode":500,"error":"Internal Server Error","message":"invalid_index_template_exception\n\tRoot causes:\n\t\tinvalid_index_template_exception: index_template [metrics-elastic_agent.filebeat_input] invalid, cause [Validation Failed: 1: [index.mode=time_series] requires a non-empty [index.routing_path];]"}
  

  However, agent.id is set as dimension and it is always present for all documents. I cannot find the reason for why this is happening, so I am removing this data stream migration from this PR.

Checklist
