[Release 0.3.1]

Notes for self-hosted etcd: The newly introduced TLS feature for self hosted etcd is a breaking change. Existing self hosted etcd cluster MUST be recreated for updating to this release.

Added

• Self-hosted etcd: if etcd-hosts.checkpoint file exists under ${datadir}/, etcd pod will restore the hosts mapping from it before etcd bootstraps.
• Add static TLS support for self-hosted etcd mode.
• The operator will now post Kubernetes events. To allow this the necessary RBAC rule for the resource events must be added to the clusterrole. See the rbac guide to see how to set up RBAC rules for the operator. If the rbac rule for 'events' is not present then the operator will continue to function normally but will also print out an error message on the failure to post an event.
• Add revision field in backup status.
• Support getting a specific backup with verison and revision from the backup service.

Changed

• Self-hosted etcd: use FQDN for client/peer URL.
• Updated RBAC rules for resources thirdpartyresources and storageclasses to all verbs * . We loose granularity early so that we have more flexibility to use other methods (e.g. Get) later.

Removed

• Update default etcd version to 3.1.8

Fixed

• [GH-1108] selfHosted: fix backup unable to talk to etcd pods
