geo-rep: Alternate command to generate SSH Keys

`gluster system:: execute gsec_create` is used to generate SSH
Keys in all Master nodes and collect public keys in command initiated
node. But this tool will not provide details if a peer node is down and
unable to generate keys.

New command will be introduced to create SSH Keys in all peer nodes.

Usage:

    gluster-georep-sshkey generate
    or
    gluster-georep-sshkey generate --no-prefix

Generates two SSH keys(one for gsyncd access and other for tar) in all
peer nodes and collects the public keys to the local node where it is
initiated. Adds `command=` prefix to common_secret.pem.pub if `--no-prefix`
argument is not set.

Shows status as below,

+-----------+-------------+---------------+
|    NODE   | NODE STATUS | KEYGEN STATUS |
+-----------+-------------+---------------+
|    fvm2   |          UP |            OK |
| localhost |          UP |            OK |
+-----------+-------------+---------------+
