[FEATURE] Add latency meter to node details

[MathNodes]

This can be handled 1 of 2 ways.

1. Upon expanding node details, create a ping to the host and display a latency meter or ms of client to node. Issue with this is, we have to first do 2 requests. One to the API to get remote uRL. second request can be the ping.

2. When user clicks "Check Details" have the detail expansion dialog display the latency from client to node.

Of these two ways, the second is the most convenient to code and will not slow down the app.
