Refactor ListSubnets #2804

Merged

  • As part of ZoneGetter initialization, generate the default subnet config to stop re-generating the config in every ListSubnets call
  • ListSubnets will always return the current list of subnets
  • TransactionSyncer syncInternalImpl depends on ListSubnets to determine which set of subnets are valid (flag gate occurs in ListSubnet). This abstracts the subnet determination to the zone getter
  • Add unit tests for ListSubnets

Looks significantly cleaner. Thanks!

Just one suggestion and one typo, else looks good to go.
