jstests/core/roles_info.js is failed with injected dollar tenant when send the following request:

 { "rolesInfo" : { "role" : "testRoleJSCoreRolesInfo", "db" : "test" } }

To reproduce it, use the command line "buildscripts/resmoke.py run --suite native_tenant_data_isolation_with_dollar_tenant_jscore_passthrough jstests/core/roles_info.js ".

Root cause: The tenant information is dropped off when parsing command parameter with auth::RolesInfoCommandArg::parseFromBSON(commandElement).

To fix it, we should change the auth::RolesInfoCommandArg::parseFromBSON(commandElement) to take in tenant information. Perhaps, the IDL compiler should also be changed to generate the correct call site code for this function.
