fixes:
- Fixes an issue which caused conductor's periodic tasks to stop executing.
See https://bugs.launchpad.net/ironic/+bug/1637210.
features:
- Adds DBDeadlock handling which may improve stability when using Galera.
See https://bugs.launchpad.net/ironic/+bug/1639338. Number of retries
depends on the configuration option ``[database]db_max_retries`` which
programmatically defaults to 5.
upgrade:
- All DB API methods doing database writes now retry on deadlock. The
``[database]db_max_retries`` configuration option specifies the maximum
number of times to retry, and can be customised if necessary. It is 5 by
default.
