prefix or public keys break meta

[igorlukanin]

Describe the bug
This data model file compiles successfully:

cubes:
  - name: meta_prefix
    sql: SELECT 123

    measures:
      - name: count
        type: count
        meta: 
          my_prefix: qwerty

However, the following data model file would not compile (take a close look at meta):

cubes:
  - name: meta_prefix
    sql: SELECT 123

    measures:
      - name: count
        type: count
        meta: 
          prefix: qwerty

It emits the following error:

cubes/meta_prefix.yml:8
        "prefix": qwerty
                  ^

ReferenceError: qwerty is not defined

Apparently, there's an issue with data model validation: prefix is not accepted inside meta if it has a value of the string type. Passing a boolean or a numeric value works.

Might be related to how Cube validates prefix inside views (docs).

Expected behavior
It should be allowed to use prefix inside meta on cube/view members.

0.35.45

Apparently, public also breaks meta in the same way.

It seems that this might been already fixed. Just tried on the current (1.2.30) - got the expected results in meta without errors:

        {
            "name": "simple_orders",
            "type": "cube",
            "title": "Simple Orders",
            "isVisible": true,
            "public": true,
            "measures": [
                {
                    "name": "simple_orders.count",
                    "title": "Simple Orders Count",
                    "shortTitle": "Count",
                    "cumulativeTotal": false,
                    "cumulative": false,
                    "type": "number",
                    "aggType": "count",
                    "drillMembers": [],
                    "drillMembersGrouped": {
                        "measures": [],
                        "dimensions": []
                    },
                    "meta": {
                        "my_prefix_string": "qwerty",
                        "another_number": 123,
                        "another_boolean": true
                    },
                    "isVisible": true,
                    "public": true
                },

So, I'm closing it for now.
