Adds an NDJSON ESQL datasource. The schema is inferred from the first 100 lines. Supported types are INTEGER, DOUBLE, LONG, BOOLEAN, DATETIME (strings in ISO format) and KEYWORD. Multi-values are supported, nested objects are flattened by joining property names with a '.' In case of parsing failure, the stream is consumed until the next end of line to recover.
