Subject: [PATCH] mgr/dashboard: support custom validator messages in inline
 edit

we can add custom messages to the customTemplate like
```

        name: $localize`Name`,
        prop: 'name',
        flexGrow: 2,
        cellTemplate: this.removingStatTpl,
        cellTransformation: CellTemplate.editing,
        customTemplateConfig: {
          validators: [Validators.required, Validators.pattern(/^[A-Za-z ]+$/)],
          errorMessages: {
            required:  $localize`This field is required.`,
            pattern: $localize`The field format is invalid.`
          }
        }
      },
```

also extend support for async validator
