We use a lot of Tunnels while running our jobs because we run many concurrent jobs. Each jenkins jobs creates its own tunnel (no sharing). We observe the following issues
1. No insight into the number of tunnels for the account. SauceLabs portal show clearly show the max tunnel limit.
2. By default the account should be pre-configured to have at least one tunnel per VM.
As a customer, I actually don't really want to deal with tunnel management. SauceLabs should handle this behind the scenes for me. I just want to buy the VM.
