[CW-1988] Disable ability for user to type the reply in the webchat.

[vitellolabs]

Is your feature or enhancement related to a problem? Please describe.

I would like to disable ability for user to type the response in the webchat, when bot sends the input_select message. At the moment user can skip the select options and continue to type.

Describe the solution you'd like

I would like to pass an argument in my json message, e.g:

{
    "content": "Select one of the items below",
    "content_type": "input_select",
    "content_attributes": {
        "items": [
            { "title": "Option1", "value": "Option 1" },
            { "title": "Option2", "value": "Option 2" }
        ]
    },
    "private":false, 
    "allow_input": false
}

Where allow_input may be used to tell client to disable the input. Of course webchat client would have to implement proper handling of this parameter.

Describe alternatives you've considered

I considered writing a client side JS to achieve this functionality but it feels like a hack rather than a solution.
