[long76]

Refs: #5066

Complex application may have many war-s and do not allow monopolize root context path(/). Add ability to remove context path(usual it's war name) from application server use @WebInitParam or just override getInitParameter for parameter GrpcServlet.REMOVE_CONTEXT_PATH

requestURI = contextPath + servletPath + pathInfo

I use Wildfly 24 and need use non root context(/) for GRPC. I can use custom path for GRPC server? On GRPC clients like Insomnia and Postman i can't put localhost:8080/grpc-war in url. This MR allow use custom context for application servers like WildFly. If i will use HAProxy or something else for proxy i can get access for GRPC server on Wildfly 24 on GrpcServlet.

No.

Insomnia and Postman

They are not real clients, but UI tools to send arbitrary requests to server for development purposes.

Yeah, there's not going to be clients that work with this. It sounds like you would get testing infrastructure running, but once you try to make real clients you're going to have problems.
