Ensuring that request-scoped config gets propagated to HttpUriRequest

The change makes the config changes introduced via
`Invocation.Builder#property(propertyName, propertyValue)` effective.
We want to use this pattern because it is truely request creation scoped.
In contrast the current implementation is only effective if config changes
are being introduced via `WebTarget#property(propertyName, propertyValue)`
which unfortunatly creates a new copy of copy of
`org.glassfish.jersey.client.ClientRuntime` which effectively makes it
innefective for implementing dynamic configuration (we saw OutOfMemory
errors due to that).

Original change can be founde here: #939

Closes #1137
