ISSUE:       6677
TITLE:       Ability to query Firebird configuration using SQL
DESCRIPTION:
JIRA:        CORE-6444
FBTEST:      bugs.core_6444
NOTES:
    [01.12.2023] pzotov
        Currently test only checks ability to query virtual table RDB$CONFIG and SQLDA.
        Records are not fetched because content of some of them depends on OS/major version and/or can change.
    [13.12.2023] pzotov
        Added 'SQLSTATE' in substitutions: runtime error must not be filtered out by '?!(...)' pattern
        ("negative lookahead assertion", see https://docs.python.org/3/library/re.html#regular-expression-syntax).
        Added 'combine_output = True' in order to see SQLSTATE if any error occurs.
