[FEATURE] Support paging system requests

[Yury-Fridlyand]

Is your feature request related to a problem?
If the main customer of SQL plugin -- JDBC driver -- uses pagination, it sends all queries as paging requests. See opensearch-project/sql-jdbc#67.

What solution would you like?
Support pagination of queries like

SHOW TABLES
DESCRIBE TABLES

{
    "query" : "describe tables like 'calcs'",
    "fetch_size" : 5
}

Currently, such request has following response:

{
  "error": {
    "reason": "There was internal problem at backend",
    "details": "'class org.opensearch.sql.opensearch.storage.system.OpenSearchSystemIndex' does not support pagination",
    "type": "UnsupportedOperationException"
  },
  "status": 503
}

Error stack:

Server side error during query execution

What alternatives have you considered?
Ignore fetch_size parameter for such queries and always return full response.

Do you have any additional context?
Implementation of that require implementing a new Physical Plan node -- PaginateOperator.
It was implemented in past and then removed in 1f6cf70 in #1497. Paging system query is not supported by legacy engine too.
