Description SATHEESARAN 2018-07-11 11:41:15 UTC 
Description of problem:
-----------------------
Automatic addition of hosts to the cluster feature will work good, only if there is SSH public key authentication for both front-end & backend IPs & FQDNS

Version-Release number of selected component (if applicable):
-------------------------------------------------------------
RHHI 2.0 deployment docs

Expected results:
-----------------
Inform user to establish SSH public key authentication from the first host to all the hosts in the cluster ( including the same host ) using:
1. Front-end IP
2. Front-end FQDN ( if exists )
3. Back-end IP 
4. Back-end FQDN ( if exists )

For example:
If there are 3 hosts - host1, host2, host3 - in the cluster and deployment will be initiated from host1

then do the following:
1. Generate SSH public & private key on host1
[ root@host1 ]# ssh-keygen

2. Copy the SSH public key to all hosts using front-end IP
[ root@host1 ]# ssh-copy-id root@<host1-front-end-ip>
[ root@host1 ]# ssh-copy-id root@<host2-front-end-ip>
[ root@host1 ]# ssh-copy-id root@<host3-front-end-ip>

3. Copy the SSH public key to all hosts using back-end IP
[ root@host1 ]# ssh-copy-id root@<host1-back-end-ip>
[ root@host1 ]# ssh-copy-id root@<host2-back-end-ip>
[ root@host1 ]# ssh-copy-id root@<host3-back-end-ip>

4.  Copy the SSH public key to all hosts using front-end FQDN
[ root@host1 ]# ssh-copy-id root@<host1-front-end-FQDN>
[ root@host1 ]# ssh-copy-id root@<host2-front-end-FQDN>
[ root@host1 ]# ssh-copy-id root@<host3-front-end-FQDN>

5. Copy the SSH public key to all hosts using back-end FQDN
[ root@host1 ]# ssh-copy-id root@<host1-back-end-FQDN>
[ root@host1 ]# ssh-copy-id root@<host2-back-end-FQDN>
[ root@host1 ]# ssh-copy-id root@<host3-back-end-FQDN>
