Enable TELNET connection

[frederic-loui]

For now, graphite web-ui authorize only SSH connection. Is there a possibility to allow plain telnet connection method ?

i.e.: In node config define OOBM_CONNECTION=[ssh,telnet] in the example above, ssh and telnet is allowed.

[edit] I enabled SSH on ContainerLab rare kind default config. So this feature request is not that urgent. But I have the feeling that enabling plain telnet is also good just for "labbing".
