[SQL] initial commit for SQL language selector
Browse files Browse the repository at this point in the history
Only adds the quick startup for OpenSearch cluster with a SQL
plugin and observability with:
```
yarn opensearch snapshot --sql
```

Also, adds SQL to the language selector stolen shamelessly from
opensearch-project#5623

Next steps to intercept and send to SQL API or just transform basic
syntax to DSL
