Support for ACL host

[qzhang1995]

I am trying to set up ACL for host using custom JulieRoles (suggested by issue #519),
Current ACLs for resource ResourcePattern(resourceType=TOPIC, name=test-topic, patternType=LITERAL):
(principal=User:ANONYMOUS, host=100.64.1.2, operation=WRITE, permissionType=ALLOW)

1. In the roles.yaml , i set up the custom role, we are using confluent platform.

---

roles:

• name: "hostACL"
  acls:
  • resourceType: "Topic"
    resourceName: "test-topic"
    patternType: "LITERAL"
    host: "100.64.1.2"
    role: "DeveloperWrite"

2. Assign the custom role in topology.yaml

---

projects:

• name: "Atest"
  hostACL:
  • principal: "User:ANONYMOUS"

3. But in the julie ACL execution log and it has wildcard value "host" : "".
   {
   "Operation" : "com.purbon.kafka.topology.actions.access.CreateBindings",
   "Bindings" : [ {
   "resourceType" : "TOPIC",
   "resourceName" : "test-topic",
   "host" : "",
   "operation" : "DeveloperWrite",
   "principal" : "User:ANONYMOUS",
   "pattern" : "LITERAL",
   "scope" : {
   "clusters" : {
   "kafka-cluster" : "***"
   },
   "resources" : [ {
   "name" : "test-topic",
   "patternType" : "LITERAL",
   "resourceType" : "Topic"
   } ]
   }
   } ]
   }

this is in the ACL list in the end of the julieOps execution log
'TOPIC', 'test-topic', '*', 'DeveloperWrite', 'User:ANONYMOUS', 'LITERAL'

Is it possible to set up ACL for Hosts? thanks.
