Add Terminal Link to Service component instance page for UI2

In UI2, Service > Component > Component Instance uses Timeline server to aggregate information about Service component instance.  Timeline server does not have the full information like the port number of the node manager, or the web protocol used by the node manager.  It requires some changes to aggregate node manager information into Timeline server in order to compute the Terminal link.  For reducing the scope of YARN-8914, it is better file this as a separate task.
