Draft: NXCALS-7086 Add findAllWithoutConfig to variable metadata api

New query:

select variableda0_.variable_id as variable_id1_18_0_,
    systemspec2_.system_id as system_id1_13_1_,
    variableda0_.rec_version as rec_version2_18_0_,

    variableda0_.description as description4_18_0_,
    variableda0_.system_id as system_id7_18_0_,

from variables variableda0_
    left outer join systems systemspec2_ on variableda0_.system_id = systemspec2_.system_id

        select variableda1_.variable_id
        from variables variableda1_
        where variableda1_.variable_name = ?
    )

Name of new method can (and should) be discussed. Alternative may be generic method findAll/One(Condition<?> condition, <? extends QueryVariant> variant), where QueryVariant may include such variants like with/without config, with/without history etc.
