Starting the web interface

[malishav]

The current flow to start the web server is to issue an RPC from openv-client with view web arguments. When this is launched, the openv-client console prints web interface logs.

This flow is a bit confusing as I would expect the web interface to be started when launching openv-server. I would recommend adding an argument to openv-server that would control the start of the web server, enabled by default. This would be similar to the --wireshark-debug and --tun arguments, already available.
