Add syntax to specify options for right joined table

[glookka]

Bug Description:

Currently there is no way to specify options like field_weights for the right table in JOIN statement. The suggestion is to use options(table_name) =... in SQL and this in json

  "options": {
    "table_name": {
       ...
    },
    "table_name2": {
       ...
    }
  }

When there's no join, options should look like this:

 "options": {
    "option": "value"
  }

@Nick-S-2018 please add the info about search options for join queries to the openapi yaml and ensure the generated clients can deal with it. The documentation can be found here https://manual.manticoresearch.com/dev/Searching/Joining#Query-options-and-match-weights
