Add option to pass props to custom components

[sorrentix]

As per title, this will let us pass the props down to custom compoents by defining them in the rules.
When using a custom component in the rule, one can set the customComponentProps to an object containing the props.

Hey @sorrentix - sorry for the long delay getting back to you on this. I'll test this out ASAP and get it merged in.

Did you fix the issue? Badly the props option is needed. @dabernathy89 @sorrentix

@sorrentix @dabernathy89 I had to do this recently using vue-treeselect, I used loadOptions to add the root options async, this can all be achieved by just extending QueryBuilderRule.vue and using a custom-component rule @see Custom templates
