Adding new use cases

[amitgalitz]

Description

This PR mainly adds a few new use cases, including there defaults and templates.
Additionally:

1. Changed neural sparse step required fields based on new upgrades made in 2.12 so only name, version and format is required
2. Added some extra escaping logic in substitution so i can handle substituting in complicated painless script
3. Added logic in create pipeline step to escape " of an array.

Some open questions:

1. I have quite a few templates that are very similar cause of slight changes in connectors, should I keep it that way for 2.13 or potentially have connectors get made with fields that are never used and that look like this:
   "post_process_function": "${{create_connector.actions.post_process_function}}"
   I was thinking it might confuse customers and not be the cleanest look.

2. For some of the more nested param I want users to have control over like the mapping and processors the keys were getting pretty nested so I tried to limit them but then it might not be as consistent. Let me know if you think this can be improved. Another potential solution is to just have the key be ${{node_id.last-field-name}} or two fields back incase they are the same like in hybrid-template.

for example now I have:
"${{normalization-processor.combination.technique}}" and "${{normalization-processor.normalization.technique}}".

this could be changed to "${{create_search_pipeline.combination.technique}}" and "${{create_search_pipeline.normalization.technique}}"

other fields like: "text_embedding.field_map.input" will change to "create_ingest_pipeline.field_map.input"

other option is keeping as is or having the full path in dot form
