Log paths provided to fluentd are incorrect for containerized deployment

[Lars Kellogg-Stedman]

The existing logging configuration assumes logs are located in /var/log (paths look something like "/var/log/nova/nova-api.log", but this is incorrect in a containerized deployment. We need to either transform the path or provide a container-specific logging configuration.

    Allow log path transformation in fluentd glue

    Logs in a containerized deployment are not in the same location as on
    a baremetal deployment. This commit adds the $fluentd_path_transform
    paramter to the fluentd glue module. This is a regular expression that
    is used to transform log paths. To use this feature, include in your
    hiera configuration something like:

        tripleo::profile::base::logging::fluentd::fluentd_path_transform:
          - /var/log/
          - /var/log/containers/

    Fluentd: Transform path by service

    Currently, the configuration delivered via
    service_config_settings does not provide the
    transformation path regarding the logs for
    containerized deployments. So logs are not
    correctly configured on fluentd on containerized
    deployments.

    This path added this feature so the logs are
    properly located on fluentd configuration.

    Added unit test for this issue
