Tap doesn't work with Rancher downstream clusters

[zilmarr]

Description

1 - Installed kubetap using krew
2 - Tried to tap an existing service running inside a cluster created and managed by Rancher
3 - Got the error below:

Error: error upgrading connection: error creating request: parse "https://rancher.mydomain.local%2Fk8s%2Fclusters%2Fc-wagrt/api/v1/namespaces/hmg/pods/app-56fd855877-4fg7c/portforward": invalid URL escape "%2F"

Kubectl commands to create reproducable environment / deployment

Using against a cluster created/managed by Rancher:

kubectl tap on app-service -p 8080 --https --browser -n hmg

@zilmarr just run it without the --browser or --port-forward options. The tap will be set up, and you can do the port forward yourself - kubetap even gives you the command to run.
