RemoteRepository update send wrong request param to REST API

[bdecarne]

Hello,

I'm trying to use delete/update feature using POST with Multi-Part Request Body via bigdata-client. It doesn't work because the HTTP request is not correct :

https://github.com/blazegraph/database/blob/1dad2d4cf1261a271d3766947be8916a7d7df761/bigdata-client/src/main/java/com/bigdata/rdf/sail/webapp/client/RemoteRepository.java#L962

It should be

opts.addRequestParam("updatePost");
