/**
* Will set fields from flags. The unused configuration can be found via the {@linkplain
* ConfigBag#getUnusedConfig()}. This can be overridden for custom initialization but note the
* following.
*
* <p>For new-style locations (i.e. not calling constructor directly, this will be invoked
* automatically by brooklyn-core post-construction).
*
* <p>For legacy location use, this will be invoked by the constructor in this class. Therefore if
* over-riding you must *not* rely on field initializers because they may not run until *after*
* this method (this method is invoked by the constructor in this class, so initializers in
* subclasses will not have run when this overridden method is invoked.) If you require fields to
* be initialized you must do that in this method with a guard (as in
* FixedListMachineProvisioningLocation).
