The log directory for nova has the default_t SELinux context and this prevents rsyslog from accessing nova's logs. This patch ensures that the file contexts are set properly for nova's logs. This change also makes nova's log directory configurable using the `nova_log_dir` variable. Closes-Bug: 1748911 Change-Id: Iaac69c5807715f50386624602375c89adeeb48a1
