Move to transports and allow developers to implement their own HTTP Clients

[ConnorLinfoot]

This update intends to remove forced built-in Apache dependency and instead allow users to select and handle their own HTTP implementation for communicating with the API including some premade transports.

There are also some other changes that have been made:

• Removes deprecated methods (excluding the getPlayerByName method).
• Rename getGameCounts to getCounts along with its new endpoint.
• Rename getWatchdogStats to getPunishmentStats along with its new endpoint.
• Moves to using a header for API Key authentication instead of a parameter.
• ExampleUtil now supports a system property for easier testing with the API Key.

These changes are a work in progress and are subject to change before release.
