sss_ssh_authorizedkeys helper missing

Issue Report

Feature Request

consider shipping sss_ssh_authorizedkeys

Other Information

this is a simple identity provider helper that can use ssh public keys stored in IPA/LDAP to log in people. it is configured in sshd_config to replace/supplement the .ssh/authorized_keys file with the keys in ldap

(just to aid confusion, this is not compatible with Kerberos as ssh key based log-in cannot issue tickets. it can be used instead of Kerberos on some environments where ssh key based login is used)
