update `solo network deploy` to conditionally create the `/opt/hgcapp/services-hedera/HapiApp2.0/data/config/block-nodes.json`

[jeromy-cannon]

• have solo network deploy check to see if block nodes is installed
• if block nodes is installed then create the /opt/hgcapp/services-hedera/HapiApp2.0/data/config/block-nodes.json file
• we can follow the same load pattern as the genesis-throttles.json which is passed into the helm chart during solo network deploy as a value to the values file override which becomes a configMap that gets copied in via the initContainers:init-copier
• instead of localhost use the FQDN for the block nodes service

example block-nodes.json format:

{
  "nodes": [
    {
      "address": "localhost",
      "port": 8080
    }
  ],
  "blockItemBatchSize": 256
}
