Subject: [PATCH] xCAT provision Sles11.2 will hang-on when excuting
 remoteshell script

xCAT provision Sles11.2 will hang-on and wait for input passphrase when executing "ssh-keygen -y -f /etc/ssh/ssh_host_ecdsa_key > /etc/ssh/ssh_host_ecdsa_key.pub" command in remoteshell script.

Root Cause: Sles11.2 install openssh-5.1p1-41.57.1 build-in package, and this version openssh don't support ecdsa key type.
So there needs a openssh support check before ecdsa key generation. In remoteshell script, line 283, we will add "ssh-keygen -t ecdsa -y -f /etc/ssh/ssh_host_ecdsa_key -P "" " command and check the result to judge support or not.
