ISSUE:       https://github.com/FirebirdSQL/firebird/issues/7818
TITLE:       Extend rdb$get_context('SYSTEM', '***') with client-related info
DESCRIPTION:
    Test assumes that QA plugin uses client library from the folder where testing FB instance was deployed,
    thus content of con.info.firebird_version is exactly the same as version of client library.
    This also causes value of CLIENT_OS_USER context variable to be equal to getpass.getuser().
NOTES:
    [01.11.2023] pzotov
    Checked on 6.0.0.104, 5.0.0.1259, 4.0.4.3009
