* Allow definition of custom network interfaces * Create network client interface class * Change to PIMPL approach * Add example for custom network clients Why: - Show users how to use multiple network interfaces This change addresses the need by: - Adding an example PIO project to use Wi-Fi and GSM/LTE * Add WebSockets prefix to normal and secure client Why: - Avoid name collision - Fix broken reconnect change This change addresses the need by: - Adding WebSockets prefix to all custom clients - Marking custom client as secure in clientDisconnect() - Remove broken fix for reconnecting
