keyfile: add NMKeyfileHandlerFlags

Browse source 
nm_keyfile_read() and nm_keyfile_write() will be public API.
As such, it must be flexible and extendible for future needs.
There is already the handler callback that fully solves this
(e.g. a future handler event could request whether a certain
behavior is enabled or not).

As additional possibility for future extension, add a flags
argument. Currently no flags are implemented.
