Retry SSH without SSH_AUTH_SOCK

[kaovilai]

On darwin, this is set by default.. may be wise to retry without inheriting this env on darwin on all ssh ops such as gather bootstrap.

installer/pkg/gather/ssh/agent.go

Lines 15 to 25 in 08aa270

	func getAgent(keys []string) (agent.Agent, string, error) {
	// Attempt to use the existing SSH agent if it's configured or use the default ssh pair generated.
	if authSock := os.Getenv("SSH_AUTH_SOCK"); authSock != "" {
	logrus.Debugf("Using SSH_AUTH_SOCK %s to connect to an existing agent", authSock)
	if conn, err := net.Dial("unix", authSock); err == nil {
	return agent.NewClient(conn), "agent", nil
	}
	}
	return newAgent(keys)
	}
