RCON port cannot be exposed through docker

[egladil]

In order to expose a port through docker it needs to be known before starting the container. But since the RCON port is always randomized this is not possible. It would be useful to have a setting of some kind for forcing the RCON port to a specific port number

Good idea we should have an optional flag to specify the RCON port.

Hi @mroote,
I think that issue should be changed to bug as rcon_port parameter is ignored and randomized every time config is loaded
FactorioRconPort is assigned random value (config.go#L176) every time loadServerConfig is called

factorio-server-manager/src/bootstrap/config.go

Line 176 in 1d42f87

config.FactorioRconPort = randomPort()
