Unable to disable -i option, which breaks authenticating via ssh-agent

[paulcdejean]

Hello in a local dev environment we are using ssh-agent: https://www.ssh.com/ssh/agent

However this library forces ssh to use the -i option, which disables authenticating via ssh agent.

When the TUNNELER_IDENTITY_FILE option is unset, the -i option should be excluded.
