Introduce textSearch SearchQuery param to find Records by search term without specifying Property Name

Why?

Some cases require developers to search across dataset without specifying property name explicitly.

```js
{ q: "neo4j tutorial" }
```

This pseudo query should perform search across the dataset by calling something like this:

```cypher
MATCH (n)
WITH n, apoc.map.values(n, keys(n)) AS values
WHERE ANY(value IN values WHERE toLower(value) CONTAINS toLower('neo4j tutorial'))
RETURN n
```
