Changes environment variable files for use with scripts

This commit adds 'export' to the environment variable files.
It also renames them with the rc convention.
git is still needed with the package install
so this commit adds that package-depenedency for the
undercloud install.

Rename and simplify foreman roles

The foreman roles, since they are already namespaces by the directory,
had an unnecessary prefix. This removes that prefix.
Also, change to use 'node_hostgroup' instead of
'foreman_node_hostgroup'.
Change the foreman playbook to match the new roles.
Add 'local_settings.sh' to gitignore. You can use local_settings.sh to
set env vars for run.sh, and source it.

Fix log collection to use 'openstack_nodes'
