docs: Perform a cross join between the already defined source with the "__ALL_NODES" table using the supplied alias. Cross joins
  have a higher precedent than other join types, so if this is called after another join was defined, the resulting cross
  join will be between the previous join's right-hand side and the supplied table.
  
  @param alias the alias for the "__ALL_NODES" table; may not be null
  @return the component that must be used to complete the join specification; never null
