HA Sync to sync API config and tokens

[babs]

It would be nice if in case of HA setup, to have API's config synced between nodes including keys and tokens.

Hey!

This is a good idea. I'll look into it a bit to see if there's an easy way to use the built-in pfSense HA Sync function or if a custom implementation will be needed.

In the meantime, there is a fairly simple way to do this from the command line now if you need something working earlier:

1. Run pfsense-api backup on the master node.
2. Copy the /usr/local/share/pfSense-pkg-API/backup.json file from the master node to the same path on the backup node. scp or rsync should be able to do this.
3. Run pfsense-api restore on the backup node.
