Rename query APIs in Logs and Metrics Client

[srnagar]

To prepare for supporting resource-centric logs queries, make the following name changes to the query APIs in Logs and Metrics clients.

public class LogsQueryClient {
 public LogsQueryResult queryWorkspace(String workspaceId, String query, QueryTimeInterval timeInterval) 
}
 
// batch query
public class LogsBatchQuery {
 public String addWorkspaceQuery(String workspaceId, String query, QueryTimeInterval timeInterval)
}

public class MetricsClient {
  public MetricsQueryResult queryResource(String resourceid, ...);
}
