This commit changes the way that photonvision interacts with nmcli to control networking on the coprocessor. Instead of modifying an existing connection, Photonvision adds new connections for DHCP and Static IP configurations. It then activiates the proper one at startup and any time that the network configuration is changed. It also now uses the interface name and not the connection name and it checks that the interface is available before making any changes. If the saved interface is not found, it updates the stored interface name and applies the network settings to the current interface. This should minimize the failure to control the network if the network interface wasn't available when PhotonVision first booted.

I added active monitoring of wired connections. It now logs when an ethernet port is disconnected and it re-initializes the network connection when it is re-connected. This should ensure that the configuration is the one that is set up in PhotonVision and not the one that NetworkManager decides to apply. It also means that, if the device is disconnected when it boots, but is then connected, it will have the right configuration applied. |

This PR changes the way that photonvision interacts with nmcli to control networking on the coprocessor. Instead of modifying an existing connection, Photonvision adds new connections for DHCP and Static IP configurations. It then activiates the proper one at startup and any time that the network configuration is changed.
It also now uses the interface name and not the connection name and it checks that the interface is available before making any changes. If the saved interface is not found, it updates the stored interface name and applies the network settings to the current interface. This should minimize the failure to control the network if the network interface wasn't available when PhotonVision first booted.
One other benefit of not altering the default configuration is that, if PhotonVision fails to run for any reason, the device can be accessed using the original networking configuration.
I've tested this on an OrangePi and so far, it is working very well.
