Andrew Boik 5c9ce53e40 Update VPN logging to use new i18n functions
For log messages in neutron/services/vpn and neutron/db/vpn, replace
_() marker functions with log-level-specific marker functions: _LI(),
_LW(), _LE() from oslo.i18n.

Also, remove _() functions for debug log messages as debug level log
messages should not be translated.
