[keycloak-dev] Reuse Apache HTTP client in the quickstarts and examples?

[Marek Posolda]

Right now, we always create new instance of Apache HTTP Client per each 
request. Like in the quickstarts [1] or in the examples [2] .

This is anti-pattern and not very good usage of Apache HTTP Client, 
which is supposed to be application-scoped object though. I know the 
point is to have examples as easy as possible. However shouldn't we 
avoid anti-patterns? Otherwise there might be possible risk that people 
will inspire and use the same pattern in their production apps :-)
