[Profling] Single-click setup from Kibana

[dgieselaar]

Closes https://github.com/elastic/prodfiler/issues/2884.

To test, go to the Profiling app in Kibana. A request to the Kibana server should be triggerend (GET /internal/profiling/v1/setup/es_resources. The response should be a 200 and look similar to this:

{
  "has_setup": false,
  "steps": [
    {
      "name": "apm_package",
      "completed": true
    },
    {
      "name": "cluster_settings",
      "completed": true
    },
    {
      "name": "ilm",
      "completed": true
    },
    {
      "name": "component_templates",
      "completed": true
    },
    {
      "name": "index_templates",
      "completed": true
    },
    {
      "name": "create_events_data_streams",
      "completed": false
    },
    {
      "name": "create_indices",
      "completed": true
    },
    {
      "name": "security",
      "completed": true
    }
  ]
}

After clicking "Setup universal profiling", a HTTP POST request to /internal/profiling/v1/setup/es_resources should be triggered. After this request has successfully completed, another GET request to /internal/profiling/v1/setup/es_resources is triggered. If this successfully completes, the Profiling UI should be displayed.

To test this locally, add the following to kibana.dev.yml:

xpack.cloud.id: "foo"
xpack.fleet.packages:
  - name: apm
    version: latest

xpack.fleet.agentPolicies:
  - name: Elastic APM
    id: policy-elastic-agent-on-cloud
    package_policies:
      - name: Elastic APM
        id: elastic-cloud-apm
        package:
          name: apm
        inputs:
          - type: apm
            keep_enabled: true
            vars:
              - name: api_key_enabled
                value: true
              - name: host
                value: "0.0.0.0:8200"
                frozen: true
              - name: secret_token
                value: "foo"

This will install the APM package and a policy that looks like the Elastic Cloud APM policy.
