[Pki-devel] [PATCH] 656 Added automatic Tomcat migration.

The pki-core.spec has been modified to execute pki-server migrate when the package is installed. This way when upgrading from F22 to F23 all PKI instances will be migrated automatically to Tomcat 8. The pki-server migrate command has been modified such that if there is no specific Tomcat version specified it will use the current Tomcat version. The top attribute in the CLI class was not functioning properly, so it has been replaced with get_top_module() method. The getopt() invocations in pki-server subcommands have been replaced with gnu_getopt() to allow intermixing options and arguments. https://fedorahosted.org/pki/ticket/1310 -- Endi S. Dewata
