Feature/#574 look at httpclient cache key (#589)

Browse Source 
* #574 consolidate some code, man the config stuff is a mess!

* #574 just use the downstream re route and the key for caching http clients

* #574 added benchmark, i was suprised to learn using a complex type was faster than a string in benchmark .net dictionary tests, hey ho probably dont have enough data in the type...
