Refactoring platform-agnostic Gnubby Auth Handler logic into a Host Extension.

This change breaks the logic in the GnubbyAuthHandlerLinux class into
platform-specific and platform-agnostic chunks.  The platform-specific
logic has remained in the GnubbyAuthHandlerLinux class whereas the
platform-agnostic code was moved into a new HostExtension class
(GnubbyHostExtensionSession).  This allows us to add a Gnubby host
extension if it is supported by policy and remove the logic and plumbing
for gnubby message handling from ClientSession and the many
DesktopEnvironment classes.
