[SLO]Ability to create SLO based on an existing visualization

[mgiota]

Relates to https://github.com/elastic/kibana/issues/174996

🍒 Summary

As part of the On-Week project I looked into how we can generate an SLO from an existing visualization. The idea is to add a new Create SLO option to the Lens visualization, which links to the slo creation form prefilled with the data view, query, filter etc. This is going to be useful for SREs, since they won't have to do the double work of defining again the queries, data view etc.

Implementation

The challenge I can already see here, is how we can map the different Lens functions into the proper SLI definition (indicator type, queries etc). There is already the option Explore Data in Discover in the Lens embeddable, so can check how they do it and reuse stuff from there)

✔️ Acceptance criteria

• Add a new ui action on the Lens embeddable called Create SLO. (Linking here an example on how to add a ui action on an embeddable)
• Sniff the metric the visualization is using
• Navigate to observability slo create page with the following information prefilled
  • indicator type
  • data view
  • total query
  • good query
  • filter
  • timestamp field

Thanks to @elkargig and @framsouza for the great idea!
