Fix examples to use [Batch|Simple]SpanProcessor (#1280) 
https://github.com/open-telemetry/opentelemetry-java/pull/1241 changed the names of
[Batch|Simple]SpansProcessor to [Batch|Simple]SpanProcessor but did not change the examples to
match. This fixes the examples so that they now build correctly.

HTTP Example

Note: This is an advanced scenario useful for people that want to manually instrument their own code.

This is a simple example that demonstrates how to use the OpenTelemetry SDK to manually instrument a simple HTTP based Client/Server application. The example creates the Root Span on the client and sends the context over the HTTP request. On the server side, the example shows how to extract the context and create a Child Span with attached a Span Event.
