Fix a few problems... No plugin should return secrets in the GetSettings method,
which some plugins did. When that was committed in the commit "system-settings:
don't return secrets in the settings", it broke those plugins that didn't implement
GetSecrets. Each plugin can actually use the same code for GetSettings and
GetSecrets, so implement those generically in the NMExportedConnection class and
remove plugin-specific implementations that all did the same thing.
* libnm-glib/nm-settings.c
libnm-glib/nm-settings.h
- Rename the "get_secrets" virtual function "service_get_secrets" to
clarify when it's used; NMExportedConnetion is a base-class for both
the client and service side, which is sort of confusing, and
get_secrets only makes sense on the service side.
* libnm-glib/nm-dbus-connection.c
- (get_secrets): remove, unused, and clients need to do extra work to
get secrets anyway since the call can block on the remote side
* system-settings/plugins/ifupdown/nm-ifupdown-connection.c
system-settings/plugins/keyfile/nm-keyfile-connection.c
- Fix up for get_secrets -> service_get_secrets
