make rate limiting whitelist a function so users can override with dynamic behaviour

Browse Source 
* Make rate-limiting client whitelist dynamic
* Refactor `RateLimitOptions.ClientWhiteList`
* Fix typo in variable `enbleRateLimiting`
* Fix case in variable `clientIdheader`
author Taiwo Otubamowo <totubamowo@deloitte.co.uk>

* fix 1045

* #492 log 500 with error log level, acceptance test, unit test

* #492 minor changes

* initial commit for new feature #1077

allow to limit the number of concurrent tcp connection to a downstream service

* protect code against value not in accurate range

add unit test

* Do not crash host on Dispose

* Add test

* Pin GitVersion.CommandLine package version

* #683 validate if there are duplicated placeholders in UpstreamPathTemplate

* Use registered scheme from Eureka (#1087)

* extra test

* very brief mention MaxConnectionsPerServer in docs

* build develop like a PR

* more docs

* test
