[Feature Request] Inject the form model into the custome validator function

Component Name

el-form

Description

Without model in validator function, I have to use this.xxx or $refs to access the model itself. It's inconvenient when I use config-like style to write a form validation.Especially when the config and the form component codes are in different repos which communicate with server's json response.

e.g

in repo1 there's component's code:

<el-form>
  <el-input/>
</el-form>

in repo2 there's form items' config:

{
  label: 'xxx',
  rule: [
    validator(rule, value, callback) {
        // how to access another field's value? Can I still use "this" keyword?
    }
  ]
}

I cannot access other fields in the scene like this. Thank you.
