`we can not exchange SSH keys between new/running and existing stopped containers` we need fix it, may be on start container check other containers keys and add ssh keys.

Updated RH, restarted, bug is still here ``` root@subutai:/home/subutai# subutai attach Container2-ac7-1-4 subutai: relocation error: /lib/x86_64-linux-gnu/libnss_files.so.2: symbol __libc_readline_unlocked, version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference root@subutai:/home/subutai#...

created RH with vagrant ``` vagrant init --minimal subutai/stretch; SUBUTAI_CPU=2 SUBUTAI_RAM=4096 SUBUTAI_ENV=dev SUBUTAI_DISK=300 vagrant up ```

I could reproduce, need to reinstall host machine to check exactly, I'll back soon with test results
