[chef] knife ec2 create, ssh hostkey mismatch

[Simon Detheridge < >]

Hi,

When regularly starting new servers with knife ec2 create, sometimes a server 
grabs an IP address already used by an older one and knife fails to bootstrap 
as it fails host key check on ssh connect.

Given strict host key checking is off anyway (i.e. it doesn't prompt me to 
accept the host key on first connect) is it also possible to prevent writing 
the new host key to known_hosts, so this doesn't keep happening?

Thanks,
Simon
