Do not use - will be removed in the next release!
Merge this into StarClusterConfig._load_plugins in a future release.
Currently used to provide backwards compatibility for the plugin kwarg for
Cluster. Cluster now expects the plugins kwarg to be a list of plugin
objects not a list of dicts. This should be merged into
StarClusterConfig._load_plugins in a future release after warning about the
change in a previous release.
