Wrong format of output in `SHOW DATABASES`

[YaroslavLitvinov]

In Embucket show databases

Embucket assumes TERSE option is specified when it wasn't ~It seems format of output is taken from show schemas statement, which is irrelevant for databases~

+------------------------------------------------------------------------------+
| created_on | name                   | kind     | database_name | schema_name |
|------------+------------------------+----------+---------------+-------------|

In Snowflake show databases

TERSE
Optionally returns output containing only the following columns:
created_on
name
kind
database_name
schema_name
Note that kind, database_name, and schema_name always display NULL because the columns are not applicable for databases.
Default: No value (all columns are included in the output)

This list of colums is used by snowflake connector

@osipovartem I didn't specify TERSE in query, so if this option is enabled by default in Embucket we should state it somehow.
