Merged UI for local and Internet testng.

[MAMedici]

I've been thinking about putting this on my RPI5's I setup as jump/utility boxes on remote networks. Right now there are two separate UI's for local and Internet results. It would be nice (particularly for giving clients access) if there were a button on the local web UI to also test and compare the Internet throughput to local throughput. I.E.,

+---------------------------------------------------------------------+
|  Your PC to your local server performance (network type)
|
|  (meter)  [download graph]  [upload graph]  [ping / jitter]
+---------------------------------------------------------------------+
| Your PC to the Internet (server location / provider)
|
|  (meter)  [download graph]  [upload graph]  [ping / jitter]
+---------------------------------------------------------------------+
| Your server to the Internet (server location / provider)
|
|  (meter)  [download graph]  [upload graph]  [ping / jitter]
| 
| Last 5 test results:
| [Date:Time]  [Download] [Upload] [ Ping / Jitter]
| [Date:Time]  [Download] [Upload] [ Ping / Jitter]
| [Date:Time]  [Download] [Upload] [ Ping / Jitter]
| [Date:Time]  [Download] [Upload] [ Ping / Jitter]
| [Date:Time]  [Download] [Upload] [ Ping / Jitter]
+---------------------------------------------------------------------+

This would help when trying to diagnose Internet performance problems. Bonus points if both the local and Internet testing and reporting UI can be deployed in a single docker-compose.
