Subject: Don't store Nova DB credentials on compute nodes
X-Git-Tag: opnfv-6.0.0~2699^2~2
X-Git-Url: https://gerrit.opnfv.org/gerrit/gitweb?a=commitdiff_plain;h=dfec68afbe99d7bba43b62304b220d8a238a8730;p=apex-tripleo-heat-templates.git

Don't store Nova DB credentials on compute nodes

Remove NovaDSN from overcloud compute.

When using the Conductor the Nova compute service
does not need access to the database. This patch
removes all references to the Nova DSN in the overcloud
compute templates.
