Consider not exposing ports by default

[pablomendezroyo]

Context

HTTP ports defined in the compose file are exposed by default by docker, and in the near future HTTPS ports could be exposed as well (see https://github.com/dappnode/DNP_DAPPMANAGER/issues/970). These might be a security hole and the user might do not want to expose such ports. However, these ports could be mandatory for the package to work properly.

To discuss

• Should be HTTP and HTTPS ports exposed by default?
• Should the user be advised which ports will be exposed during the package installation?
• Should we set a boolean flag in the setup-wizard to ask the user to expose or not the ports during the package installation?
• ?

Another approach would be to to have a button to disable this expose ports
