Add preliminary work for HTTP health endpoint (#68)
* Add preliminary work for HTTP health endpoint

* Http: Fix infinite loop bug in Tx509KeypairGenerator::generateKey()

* update commandline

* Add TLS Support class for use with http server

* Add preliminary HTTP Server; TLS still broken; fix in later commit

* Fix TLS handshake, due to server being unable to serve key/certfile in 'Http.h/Http.cpp'; Cause was httlib not being threadsafe due to being a blocking http library

* Run clang format

* Add option to configure http server port via ServerConfig

* TConfig: add HTTPServerPort to config parsing step

* Fix SSL Cert / Key path not auto generating when not existing

* Add health endpoint; Fix SSL Cert serial no. not refreshing when regenerating

* Switch arround status codes in /health route

* Run clang format
