Add querying of ssh-related config values
Add querying of ssh-related config values

To allow various command-line operations like renew-crypto and node
adds to know how to generate SSH keys, some config values need to be
queried outside of LUs. This patch adds the ssh_key_type and
ssh_key_bits to the config values that can be queried.
