WAMP: fix IDE/CLI client TLS support, fix runtime client connection, add minimal certificate manager.

- IDE/CLI now takes certificate from cert directory in project, using hostname.cert as file name
- runtime connects from reactor thread instead of main thread (non thread safe, leading to systematic reconnect at start)
- certificate manager only supports returning certificate path based on hostname for now
