#3781 remoteshell while clause can infinite loop

[Lissa Valletta]

customer points out that when we have failure to be able to get the ssh host keys, the following clauses can infinite loop. We need to add some sort of loop limit.
MYCONT=cat /etc/ssh/ssh_host_dsa_key
while [ -z "$MYCONT" ]; do

.
.
.
MYCONT=cat /etc/ssh/ssh_host_rsa_key
while [ -z "$MYCONT" ]; do
.
.
.

MYCONT=cat /root/.ssh/id_rsa
while [ -z "$MYCONT" ]; do
