Freezer client reports misleading error when backup path is non-existant

Freezer displays a misguiding error when you try to backup path or file that does not exist. The other starnge thing is although it returns a "Critical error" it still creates the backup containers for that execution.

Found in:
=========
zahari@zahari-z420:~$ freezerc --version
freezer version 1.1.2

Example:
========
zahari@zahari-z420:~$ swift list

zahari@zahari-z420:~$ freezerc --action backup --path-to-backup /tmp/kiss_me --container TEST199 --backup-name backup1
log file at /var/log/freezer.log
[*] Critical Error: Error: Please ALL the following options: --path-to-backup, --backup-name

zahari@zahari-z420:~$ swift list
freezer_TEST199
freezer_TEST199_segments
========

Correct behavior should be to report helpful error message that path is non-existant and to fail all further actions so no Swift containser should be created.
