Deploy default and support custom affinities (#319).
Added OLM bundle files (#328).
Extend cluster resources for status and cluster operation (paused, stopped) (#337).
Cluster status conditions (#339).

Changed

[Breaking] Moved top level config option to clusterConfig (#326).
[BREAKING] Support specifying Service type. This enables us to later switch non-breaking to using ListenerClasses for the exposure of Services.

Use build_rbac_resources from operator-rs (#342).

Removed the --debug flag for HDFS container start up (#332).
