Before this change when a 403 error was encountered, such as failure to
have the permission to perform an operation, the user would get logged
out from UI pages written in the AngularJS framework. For example, if an
admin user lacks the get_project permission and tries to access the
images page, project->compute->images, the 403 will forcibly log out
the user.
This change keeps the user logged in when a 403 error is encountered and
displays an error message. The change only affects AngularJS pages.
