We need linode-api4 5.29 to assign firewalls to newly created linodes.
We can assign a firewall to newly created linodes if the user sets a firewall_label in `vars`
Add the firewall_label variable to vars that allows setting a firewall when deploying linodes
Use the rdns name for the linode rather than the IP when doing ssh since this allows corporate DNS servers to reroute traffic through their own proxies.
If a `domain_name` is configured in `vars`, then we should also add these hosts to DNS. Before adding, we will remove any stale records. The hostname in `kafka_data` is used to generate self signed certificates. If we're using a FQDN name to connect to kafka, then the certificate needs to have this FQDN as well.
…nce.label for everything else
This commit checks which kafka instances have already been created before trying to create new ones. It will only create instances that do not already exist. instance_list gets us information about all instances in a single call which is more efficient than looping through instance_info just to check if an instance has been created.
…iously created cluster id
Use VPC instead of private IP A VPC allows us to restrict connectivity between our cluster hosts and disallow connections from other hosts on the linode private network.
