Description
Is your feature request related to a problem? Please describe.
Collector has the concept of feature gates. When running the help command one can see (some?) features in the --feature-gates flag, e.g.
--feature-gates flag Comma-delimited list of feature gate identifiers. Prefix with '-' to disable the feature. '+' or no prefix will enable the feature.

This output is quite unreadable and does not expose any metadata about individual features.
Describe the solution you'd like
Create a features command that will print a summary of all features and their metadata. The command can optionally accept a specific feature ID to limit the output to just one feature.
Describe alternatives you've considered
There is a way to see the features via zpages extension http://localhost:55679/debug/featurez, but it's not always enabled and is overall a harder way to get to the same info than a CLI command.
