enables listener on 1883

fixes #1

recreated since #2 was closed by accident.

❓ question(non-blocking): Not sure, but it seems that since version 2 we also have to set allow_anonymous to true explicitely... No?

[martinbra]

yes, starting with mosquitto 2.0 users have to explicitly allow anonimous connections. It's a security reason, and I think we should keep with the "allow_anonymous false" standard, maybe create a comment to warn users about it and how to enable it. Something like:

## Authentication ##
# By default, Mosquitto >=2.0 blocks allow_anonymous authentication. Uncomment the next line to allow it.
# allow_anonymous true

What do you think?

[vvatelot]

Or, maybe the best thing is to enable authentication by default (like it works today with the admin/password login). And update the documentation saying that it is not optional but it is the default behaviour...

[martinbra]

## Authentication ##
# By default, Mosquitto >=2.0 allows only authenticated connections. Change to true to enable anonymous connections.
allow_anonymous false

like this?
Maybe we should add to the documentation (or a cmd/shell file) on how to update the password?

Yes, this seems great!
About password change, I wrote this in the readme, but maybe it should be more explicit?

⛔ Issue(blocking): As discussed in #1 we have to freeze the docker version to eclipse-mosquitto:2 to be sure the configuration fits right with the version

The added listener can be used with both versions I think. Its a default listener on 1.x and enables "clear text" communication on 2.0.

Do you want me to add it in this PR?

I was referring to this reply where I proposed to have:

• A version 1 frozen on mosquitto 1.6 (already done)
• A version 2 frozen on mosquitto 2, with the corresponding configuration file (that you fixed in this PR)
