Add local private key guard

Private key can be retrieved from OpenStack during keypair creation
only. Subsequent attempts to do so will result in getting an empty
string. If private key already exists on the local machine and there is
no guard local private key will be overwritten with an empty file.

This patch adds local private key guard which allows subsequent runs of
"create.yml" playbook without erasing local private key.
