Add additional Wifi features

[ikstream]

• set wifi credentials in menuconfig like style
• add target port and address in menuconfig like style
• IPv6
• handle 'no wifi available' situations

Instead of specifying any host:port configuration, how about a zero-config approach? Aquire the network via dhcp and use the networks broadcast address with the default influxDB port.

No wifi situations should be no problem if we use a mailbox like queue (single slot, which will be overwritten regardless if it was used) for the wifi log endpoint

That could be a default, but we should definetly allow some kind of configuration, to ease deployment.
Basically we could create something like a .config file with all relevant Build Variables set.

Its more like a reminder, that it should not block the execution of anything, if no wifi AP is available and maybe allow a check if the device is connected to a network.
