Make ::tripleo::profile::base classes work with multiple nodes
In the Next Generation HA architecture a number of active/active services will be run via systemd. In order for this to work we need to make sure that the sync_db operation only takes place on the bootstrap node, just like it is done today for the pacemaker profiles. We do this by removing sync_db as a parameter and instead set it to true or false depending if the hostname matches the bootstrap_node as it is done today in the pacemaker role. Note that we call hiera('bootstrap_nodeid', undef) because if a profile is included on a non controller node that variable will be undefined. The following testing was done: - HA puppet-pacemaker.yaml scenario with three computes - NonHA with one controller - NonHA with three controllers Fixes-Bug: 1600149 Co-Author: cmsj@tenshu.net Change-Id: I04a7b9e3c18627ea512000a34357acb7f27d6e0e Implements: blueprint ha-lightweight-architecture
