[strongSwan] Parsing strongswan.conf in starter

Any tool (including starter) building upon libstrongswan automatically
can make use of strongswan.conf options. The file is parsed during
library_init(), and options can be queried using the
lib->settings->get_* functions provided by the settings_t class.
