Update logging api example

[johnman]

Updated the logging api example:

• Updated it to a platform
• Added a window with two views to show console logs from views appearing alongside console logs from platform provider in app log.
• Updated response from server when uploading app logs to return response expected from the RVM.
• Updated runtime args to use a security realm for isolated and to reduce verbose logs.
• Added ability to clear log panel from provider and views.
• Added easy option to generate a console log messages through buttons
• Added easy option to log through a channel api contract through buttons (the provider is the source and the provider and views use it to log using an alternative approach).
• Added an example of using the Origin Private File System to write logs to file (which works in browsers and OpenFin container).
• Added additional button to read the log file from the Origin Private File System, send it to the server and clear it.
• Updated the server to support sending a custom log file from the Origin Private File System.
• Added a launch.json that debugs the logging api server.
