Fix audit log parse error

[Ganeshrockz]

Changes proposed in this PR:

• Fixes a bug in parsing the following audit log helm configuration

server:
  auditLogs:
      enabled: true
      sinks:
        - name: My Sink
          type: file
          format: json
          path: /tmp/audit.json
          delivery_guarantee: best-effort
          rotate_duration: 24h
          rotate_max_files: 15
          rotate_bytes: 25165824

where rotate_max_files and rotate_bytes get passed as string inputs to the server configuration file. This PR makes sure to perform special handling for rotate_max_files and rotate_bytes where they don't get passed with quotes.

Generated config (Before the fix)

    {
      "audit": {
        "enabled": true,
        "sink": {
          "MySink": {
              "delivery_guarantee": "best-effort",
              "format": "json",
              "path": "/tmp/audit.json",
              "rotate_bytes": "12455355", // note the presence of braces here
              "rotate_duration": "24h",
              "rotate_max_files": "20",
              "type": "file"
          }
        }
      }
    }

Generated config (After the fix)

    {
      "audit": {
        "enabled": true,
        "sink": {
          "MySink": {
              "delivery_guarantee": "best-effort",
              "format": "json",

          }
        }
      }
    }

Can we do this

 "{{ $element.name }}" : {{ $element | toJson }}

instead of https://github.com/hashicorp/consul-k8s/pull/2905/files#diff-46b4101175c7cfa3c393941b3563a31d9c7f1c49f8b709b9f87e9d97e2da181eR202-R212
