Check_MK Werk 8674: Do not require a "hostname|" prefix when querying services columns in the host table.

ID: 8674 Title: Do not require a "hostname|" prefix when querying services columns in the host table. Component: Livestatus Level: 1 Class: New Feature Version: 1.4.0i4 While the requirement makes sense for the servicegroups table (there can be multiple hosts with the same service), it is actually harmful when querying the host table: One can't formulate queries like "give me all hosts which don't have service FOO". To keep backwards compatibility *and* enabling such queries, the "hostname|" prefix is optional for those columns in the host table now.
