[FEATURE REQUEST] MQTT: port setting, username/password length, domain name as server address #493

Hi, I think these additional settings should be implemented for MQTT

MQTT TCP port setting, should also be available (like "7883")
username and password for MQTT should be larger. Some brokers (commercial) provide tokens that are more than 80 characters long. But probably there is also a request to be able to establish secure (SSL/TLS) connection. Maybe / Probably this is out of scope for this device.
instead of IP address for MQTT broker there should also be an option to insert server by domain name, like for instance: "http://mqtt.flespi.io/"

Maybe all of these parameters could be settable from WEB?

Best regards, Gregor

I think setting the port could be done in a way like web browsers do it, i.e. with a colon after the IP. Longer variables can simply done by the user by changing the respective variable in BSB_LAN_config.h. DNS resolution would certainly be necessary if users want to use MQTT broker outside the home network. Will have to look into that if that's easily doable.

I would also appreciate DNS resolution.

I have just added functionality for using hostnames (IP addresses are still possible, too) and an optional port number that can be added after a trailing colon. For example: 192.168.1.20:1884 broker.local:1884 work now. If you omit the port number and the colon, the default port 1883 will be used.
