Ability to run builtin validation checks via CLI

Overview

We have builtin checks in the framework which is not enabled by default - https://framework.frictionlessdata.io/docs/guides/validation-checks#table-dimensions. We want a way to enable them via CLI.

I think in general we need to provide a JSON interface to do so. It will be a universal way that supports all the builtin checks and all the enabled via plugins custom checks.

$ frictionless validate table.csv --checks '[{"code": "table-dimensions", "numRows": 10}]'

On the other hand, we might need to provide some shortcuts for most common conditions (again similar for the dialect API). For example:

$ frictionless validate table.csv --forbidden-values 'columnName:value1,value2,value3' --formula 'columnX > columnY`

@shashigharti @aivuk Let’s discuss what options we’d like to expose

Human readable syntax brainstorming:

$ frictionless validate table.csv --checks duplicate-row deviated-cell forbidden-value:values=a,b,c

@aivuk The default JSON interface is still good to have as:

• it’s a universal way for FD
• we use the same for dialect/etc
• it will work for any checks added in the future
• it can be used for non-human CLI usage (JSON stringified)

Another question is that the second way of providing checks might be exactly as you suggest. Of course, it will require some smart CLI coding:

providing two checks might be a problem for this syntax

$ frictionless validate table.csv --check CHECK_CODE1 --PARAM_NAME1 PARAM_VALUE1 --PARAM_NAME 2 --PARAM_VALUE2 CHECK_CODE2
