bugfixes for openswitch shared module

This commit fixes two bugs in the openswitch shared module.  The first
bug was a wrong argument type for the use_ssl argument.  It was set
to int and should be bool.  The second changes the default ports for http
(was 80, now 8091) and https (was 443, now 18091).  This change aligns
the default port values with the OS
