NEO: add a neoctl wrapper in every partition with an admin node

The purpose of the added script is to shorten calling neoctl by removing the
need to constantly supply things SlapOS can provide on its own like
certificates and admin address. A sample command is now as simple as:

    ~/srv/runner/instance/slappartX/bin/neoctl set cluster STARTING_BACKUP
