DefaultCliFeatureFlags is used to populate an initially empty config file with default values for feature flags. The keys MUST be in the format "features.<plugin>.<feature>" or initialization will fail. Note that "global" is a special value for <plugin> to be used for CLI-wide features.

If a developer expects that their feature will be ready to release, they should create an entry here with a true value. If a developer has a beta feature they want to expose, but leave turned off by default, they should create an entry here with a false value. WE HIGHLY RECOMMEND the use of a SEPARATE flag for beta use; one that ends in "-beta". Thus, if you plan to eventually release a feature with a flag named "features.cluster.foo-bar", you should consider releasing the beta version with "features.cluster.foo-bar-beta". This will make it much easier when it comes time for mainstreaming the feature (with a default true value) under the flag name "features.cluster.foo-bar", as there will be no conflict with previous installs (that have a false value for the entry "features.cluster.foo-bar-beta").
