Quick start fixes (#269)

* Correct quickstart to properly set armadaUrl

Armada url used to be specified under armada.url

Now it is specified under apiConnection.armadaUrl

* Adding ForceNoTls flag in ApiConnectionDetails

Sometimes the executor needs to be forced to use no TLS
 - Currently only uses no tls when connecting to "localhost"

This allows me to use ForceNoTls in the quickstart, as we aren't connecting to localhost and instead a specific ip address

* Fixing setting forceNoTls in quickstart
