Tyler Hobbs updated CASSANDRA-7356:
-----------------------------------

    Attachment: 7356_fix_v2.txt

7356_fix_v2 moves the check for replacing after having already bootstrapped instead of removing it entirely.  I put this through a few bootstrap, replace_address, and replace_address_first_boot tests with ccm locally.

> Doing a host replacement with cassandra.replace_address works well, but it is operationally difficult because the flag needs clearing once the replace is successful. Most people will launch through some scripts so remembering to clear the flag is a pain. Forgetting means the node won't come up on a restart.
> We should have a flag like cassandra.replace_address_first_boot that works the same as auto_bootstrap/initial_token: it is totally ignored if the node has successfully bootstrapped but on starting from a clean disk it will work as the existing cassandra.replace_address.
