> Improve the UpdateRecord processor for field removal:
>  * *Improvement 1* - In case, "Replacement Value Strategy" is set to "Record Path Value", then add a boolean property that would default to false and if true would remove the fields provided in the dynamic properties after the updates have been done. This would provide the capability to move fields in the schema.
>  * *Improvement 2* - In case, "Replacement Value Strategy" is set to "Record Path Value", allow the users to set the empty string as the value of the paths provided through dynamic properties. This would provide the capability to remove fields.
> Example - *input*
>  
> {code:java}
> {
>   "foo": "value",
>   "record": {
>     "subrecord": {
>       "key": "value"
>     }
>   }
> }{code}
> *Improvement 1*
> *Dynamic property: /subrecord => /record/subrecord*
> *Additional property set to true*
> *Output*
> {code:java}
> {
>   "foo": "value",
>   "subrecord": {
>     "key": "value"
>   }
> }{code}
>  
> *Improvement 2*
> *Dynamic property: /record => <empty string>*
> *Output*
> {code:java}
> {
>   "foo": "value"
> }{code}
