Replace reproducer argument for consistency.

This patch replaces the reproducer argument in the
prepare_undercloud_deploy method for a reproduce_command
one, to be consistent with the same naming being used
in the tripleo_deploy.py library.

Also, this patch adds a release note for the exposition of
this new CLI option in the undercloud commands.

+    Expose the existing --reproduce-command from `openstack tripleo deploy`
+    CLI in the Undercloud CLI commnads.
+    A new CLI option --reproduce-command is available for the `openstack
+    undercloud install` and `openstack undercloud upgrade` commands, which
+    creates an script, named ansible-playbook-command.sh, in the Undercloud's
+    deployment artifacts directory. This script allows running the Ansible
+    playbooks for deployment or upgrade in the same way the CLI command does.
