Move obliterate reconnection under separate flag and improve behavior

[anthony-murphy]

The obliterate logic for reconnect is not well defined. This change puts that behavior under a separate flag to ensure reconnects with obliterate are only done intentionally. Secondarily, this change modifies how it works with reconnect when there is a remote obliterate, and a local insert. The change essentially rolls back the insert, rather than having it bypass the obliterate.
