Messaging micro-service: New index - tracardi-message-bus

[atompie]

We need to create index that will be able to store this data:

{
  "type": "require-consent",
  "profile_id": "<profile-id>",
  "properties": {
    "url": "//tracardi.com/event",
    "event": {
      "grant": "consent-grant",
      "deny": "consent-deny"
    },
  },
  "call": {
    "file": "gdpr.min.js",
    "func": "main"
  },
  "expire": "<timestamp-when-message-expires>",
  "postpone": "<timestamp-when-trigger-message>"
}
