[SLO] POC SLOs with Nginx Integration

[muthu-mps]

• The package-spec release 3.3.0 allow us to add the SLOs to the integration. Now we are able to include the SLOs in the Kibana directory and install the integration.
• As a next step when we install the integration the SLOs should get created by the Fleet API.
• The Fleet API should add support for the following,
  • Add SLOs defined in the integration. There can be multiple SLOs created.
  • Update the SLOs if the id already exists. There should be a clear indication in the UI that these SLOs are created from the integration.
  • Delete the SLO when its deleted from the integration.

Please find my observations while installing the SLO from the integration,

Install SLO

• While shipping the SLO, we define the index parameter to load the data from the specific index. In general the SLO creation page from the Kibana UI supports only the logs-* and metrics-* indices.
• When I added logs-nginx.* as index name. This created a temporary data view in the SLOs. But it doesn't load the timestamp field from this temporary view.
• Based on the above observations we will keep the logs-* or metrics-* as default values and then apply the query filter to filter the data from a specific dataset.

Closing the POC task, since this has been tested and a draft PR has been created. We will merge the PR once the fleet change gets merged.
