Allow to create tables with JSON

What does this MR do and why?

Introduce an additional way of creating tables using JSON and code blocks.

    ```json:table
    {}
    ```

• Add support to render table using JSON
• Limit configuration of table
• Add test coverage
• Add error handling for when JSON parsing fails
• Add sorting capabilities
• Add filtering capabilities
• Add distinguishing element apart from other tables (added caption)

Simplest example with just data points(items)

{
    "items" : [
      {"a": "11", "b": "22", "c": "33"}
    ]
}

---

Explicitly specifying column names(fields)

{
    "fields" : ["a", "b", "c"],
    "items" : [
      {"a": "11", "b": "22", "c": "33"}
    ]
}

---

Not all items need to have all fields.

{
    "fields" : ["a", "b", "c"],
    "items" : [
      {"a": "11", "b": "22", "c": "33"},
      {"a": "211", "c": "233"}
    ]
}

When fields is not explicitly specified, the column labels are picked from the first element of items

{
    "items" : [
      {"a": "11", "b": "22", "c": "33"},
      {"a": "211", "c": "233"}
    ]
}

---

Explicitly specifying custom column label

{
    "fields" : [
        {"key": "a", "label": "AA"},
        {"key": "b", "label": "BB"},
        {"key": "c", "label": "CC"}
    ],
    "items" : [
      {"a": "11", "b": "22", "c": "33"},
      {"a": "211", "b": "222", "c": "233"}
    ]
}

---

Sortable columns

{
    "fields" : [
        {"key": "a", "label": "AA", "sortable": true},
        {"key": "b", "label": "BB"},
        {"key": "c", "label": "CC"}
    ],
    "items" : [
      {"a": "11", "b": "22", "c": "33"},
      {"a": "211", "b": "222", "c": "233"}
    ]
}

---

Table with filter

{
    "fields" : [
        {"key": "a", "label": "AA"},
        {"key": "b", "label": "BB"},
        {"key": "c", "label": "CC"}
    ],
    "items" : [
      {"a": "11", "b": "22", "c": "33"},
      {"a": "211", "b": "222", "c": "233"}
    ],
    "filter" : true
}

Error message

{
    "items" : [
      {"a": "11", "b": "22", "c": "33"}
    ],
}
