`UtilsApi` will return MVA type list value as string

[scruel]

According to your document:
https://manual.manticoresearch.com/Creating_a_table/Data_types#Multi-value-integer-(MVA)
We will be able to obtain a list for MVA type value.

However, by using UtilsApi to query the index, it won't act as the same:

>>> utilsApi.sql('CREATE TABLE products(title text, product_codes multi)')
[{'total': 0, 'error': '', 'warning': ''}]
>>> utilsApi.sql('select * from products')[0]['columns']
[{'id': {...}}, {'product_codes': {...}}, {'title': {...}}]
>>> utilsApi.sql('select * from products')[0]['columns'][1]
{'product_codes': {'type': 'string'}}

@Nick-S-2018 pls check why the client returns {'product_codes': {'type': 'string'}} in this case. I can't reproduce via JSON:

➜  ~ mysql -P9306 -h0 -e "drop table if exists products; CREATE TABLE products(title text, product_codes multi); insert into products values(1, 'abc', (1, 2, 3));"

➜  ~ curl -s 0:9308/sql -d 'query=select%20*%20from%20products'|jq .
{
  "took": 0,
  "timed_out": false,
  "hits": {
    "total": 1,
    "total_relation": "eq",
    "hits": [
      {
        "_id": "1",
        "_score": 1,
        "_source": {
          "title": "abc",
          "product_codes": [
            1,
            2,
            3
          ]
        }
      }
    ]
  }
}

@sanikolaev The issue can be reproduced by calling the /sql?mode=raw endpoint which is what the client does internally.
However, the multi type (as well as multi64g or json) is actually returned as string in sql queries, so we need to discuss this case further.

@scruel If you need info about column data types, the best way to get it is to use the desc command instead:
utilsApi.sql('desc products')

@Nick-S-2018 Such auto-conversion already implemented in searchApi, why not let utilsApi also utilize it?

@scruel
searchApi and utilsApi use different API endpoints on the server side so they operate with different response formats
