Change the contact's system groups.
The system groups are a property exposed by Google Contacts address books, and can include any combination of the following identifier: - "Contacts" - "Family" - "Friends" - "Coworkers"
Setting the system groups will also change the group membership to include the localized version of those groups, and may change the value of Edsf.Persona.in_google_personal_group.
Attempting to call this method on a persona beloging to a PersonaStore which is not Google will throw a PropertyError.
It's preferred to call this rather than setting Persona.system_groups directly, as this method gives error notification and will only return once the groups have been written to the relevant backing store (or the operation's failed).
