7f46da223d client: no need to getToken when dial specific endpoint for maintenance 
The existing client may connect to different endpoint from the
specific endpoint to be maintained. Maintenance operations do not
go through raft at all, so it might run into issue if the server
hasn't finished applying the authentication request.

Let's work with an example. Assuming the existing client connects to
ep1, while the user wants to maintain ep2. If we getToken again, it
sends an authentication request, which goes through raft. When the
specific endpoint receives the maintenance request, it might haven't
finished previous authentication request, but the new token is already
carried in the context, so it will reject the maintenance request
due to invalid token.

We already have retry logic in `unaryClientInterceptor` and
`streamClientInterceptor`. When the token expires, it can automatically
refresh the token, so it should be safe to remove the `getToken`
logic in `maintenance.dial`
