Remove dns from existing compose files and from the pkg installer

[pablomendezroyo]

Depends on #1589 and #1588

Once the docker aliases migration is done, dappnode packages should not require anymore to have the BIND package as DNS server and the functionality setDappnodeComposeDefaults should not write anymore the DNS on new packages isntalled

[dappnodedev]

The actions to be made in order to remove the bind as DNS server are:

1. Publish the dappmanager (and core) with a migration that removes all the bind as dns from the docker-compose files of all the installed packages -> Remove bind as DNS server from compose files #1646
2. Wait for some time so that the users and the auto updates can trigger the restart of the packages. When the containers are restarted, they will get the new configuration (i.e. they are not using bind as DNS server anymore)
3. Publish a new dappmanager (and core) removing the nsupdate module and doing docker compose up of all the packages (doing directly up will only restart those that have a new configuration) -> Remove nsupdate module #1645
4. Publish the new bind -> https://github.com/dappnode/DNP_BINDv2
