Missing information on getMetadata endpoint

[ishantiw]

Expected behavior

When system:getMetadata it should return all the information regarding, endpoints, events, commands and assets.

Actual behavior

When system:getMetadata is called there are some information which is missing regarding modules. Also, endpoint info is partial or fully missing for some modules. Below is the list of some modules and missing information but would be better to double check all the modules once.

pos - events
Interoperability - sidechain/mainchain - endpoint is not updated
validators - events, endpoints
Auth - endpoints

Steps to reproduce

Call RPC system_getMetadata and observe the response

Which version(s) does this affect? (Environment, OS, etc...)
