Should metadata include all schema bundle even not support?

No, you do not need to include everything. You only need to include schemas and namespaces your service implements.

Generally speaking, OData clients will use properties like "@odata.context" and "@odata.type" in conjunction with "$metadata" to look up definitions. So, if your service reports "#ComputerSystem.v1_5_0.ComputerSystem" as a value for "@odata.type", then "$metadata" needs to contain a reference to the "ComputerSystem.v1_5_0" namespace.

There's a bit more info about this found in section 5 (Metadata document) of our Redfish and OData White Paper here: www.dmtf.org/sites/default/files/standards/documents/DSP2052_1.0.0.pdf
