Hardcoded console URIs (gns3+telnet)

[akrpic77]

When gns3 server is deployed in "cloud" and accessible only via HTTP(S), hard-coded console URLs don't make sense, as nothing is listening at the node.console port, ... there should be option to go over websocket to access the console. maybe gns3+telnet+ws ?

In log-console.component.ts:

 `gns3+telnet://${node.console_host}:${node.console}?name=${node.name}&project_id=${node.project_id}&node_id=${node.node_id}`

by modifying gns3-gui (add %N for node uuid, and %w for ws://), I managed to access console from gns3-gui over websockets using this as a Custom Console:
xterm -T "%d" -e "bash -c '(websocat --exit-on-eof --binary tcp-listen:127.1.0.1:%p %w/v2/projects/%i/nodes/%N/console/ws &) && telnet 127.1.0.1 %p'"

this could also be done with gns3-webclient-pack, relaying console access over websockets
