geo-rep: Add support for non standard AuthorizedKeysFile location

Browse Source 
In /etc/ssh/sshd_config, AuthorizedKeysFile can be customized
using %u and %h variables, %u will be replaced by user name
and %h will be replaced by home dir name. Default location is
.ssh/authorized_keys

For example,
AuthorizedKeysFile .ssh/authorized_keys
AuthorizedKeysFile %h/.my_secret_dir/authorized_keys
AuthorizedKeysFile /etc/ssh/keys/%u/authorized_keys

PS: Support only added for %h and %u in sshd_config
