Yum local

[scimerman]

• The local_yum_repository variable (inside static_inventories/) defines if the local yum repository should be created on the machine or not.
• Role creates a local yum repository, within lyr_dir_path directory (default path is /var/local/repo/).
• It is working with the other repository systems (Pulp, Spacewalk, default system repositories), but its priority is above all of them - that means packages will be first fetch from local repository and if not found, then they will be searched on others
• Setting the local_yum_repository to false will remove the repository file from the /etc/yum.repos.d/ folder on the machine, but will keep the repository's folder intact.
• The role has been added to the single_group_playbooks/cluster_part1.yml:
  - {role: yum_local, when: local_yum_repository == 'true' }
• After the user manually uploads the .rpm's into the folder on the machine, it also needs to execute createrepo /path/to/repo/folder in order for the .rpms to appear on yum [search|install} commands

Two minor phrasing/typo comments. Great work!
