v2.2.0

Overview

Bug-fixes and tt pack systemd improvements.

Changed

• tt pack generates a separate systemd unit for each packed application.
  Common (all instances) unit is removed.
• tt pack default data, run, log files location is changed for rpm/deb
  packages to /var/[log | run | lib]/tarantool/<env_name>
• create /var/[log | run | lib]/tarantool/<env_name> on target system
  for packed applications.

Fixed

• tt start: not working on FreeBSD.
• tt pack and tt build fail in verbose mode with "invalid argument"
  error.
• tt pack packs applications, which are not valid: instances file is
  empty, for example.
• tt pack with --use-docker fails due to incompatible versions of tt
  between local system and docker container. Install current tt version
  in docker image if possible.
• tt binaries list invalid argument error if tarantool is not a symlink.
• if a user provides pre or post install script to tt pack rpm, it
  uses file name as a script instead of its content.
