Server use-case with no touch

[mchack-work]

Consider having your TKey attached to a server box running, say, Ansible Tower or something and using the tkey-ssh-agent to provide ID for Ansible's ssh sessions. No one is there to touch the TKey touch sensor when needed.

We have support in both tkey-ssh-agent and tkey-device-signer to compile it with TKEY_SIGNER_APP_NO_TOUCH but no packaging for this use case. Maybe supply packages and more documentation on how to use?
