`LiveAlgorithmSettings.cs` is missing brokerages

[DerekMelchin]

Expected Behavior

We can deploy live algorithm via the QC API for every supported brokerage in cloud.

Actual Behavior

LiveAlgorithmSettings.cs only has definitions for 6 of the supported brokerages, so we can't deploy live algorithm via the QC API for every supported brokerage.

Potential Solution

Add class definitions for the missing brokerages.

The GDAXLiveAlgorithmSettings and TradierLiveAlgorithmSettings constructors also need an environment argument, like how the OandaLiveAlgorithmSettings has.

Closing as we are going to be moving API support to the lean CLI
