Need to disable GSSAPIAuthentication in /etc/ssh/sshd_config

[Timur Nurlygayanov]

Steps to Reproduce:
1. Install Fuel master node
2. Login to this nove via ssh

Observed Result:
User should want several secconds before the password promt (this is known issue of CentOS default configuration)

Expected Result:
User want to enter password without timeout with several secconds.

How we can fix it:
by default we can see in the /etc/ssh/sshd_config file:
# GSSAPIAuthentication no
but this is settings actually is enabled (iit is strange, but it is true)
to fix this problem we should remove '#' in this line, save the file and restart sshd:
root# cat /etc/ssh/sshd_config
...
GSSAPIAuthentication no
...

root# service sshd restart

    Disable sshd GSSAPI auth

    GSSAPI is not currently implemented in Fuel, so
    it only slows incoming SSH connections. Disabling
    it will enhance user experience.

We won't be fixing low or medium bugs for 5.0.x any longer. If this needs to be addressed we need to increase priority
