  1. Handle zero byte ssh key files 

    Sometimes, due to file system corruption from a linux kernel crash or for some
other reasons, the system may be left with zero byte ssh keyfiles. These zero
byte files are of no use and generate errors like the following upon next
reboot:
sshd[1454]: Unable to load host key: /etc/ssh/ssh_host_rsa_key
sshd[1454]: Unable to load host key "/etc/ssh/ssh_host_ecdsa_key": invalid format

Therefore, we should check for the presence of zero-byte files and if found
delete and regenerate the key files in order to recover from the error.
