KAFKA-17277: [2/2] Add feature dependency command to the storage and the feature command tool

[rreddy-22]

This patch belongs to the ongoing efforts of implementing KIP-1022.

Added feature-dependencies command to look up dependencies for a given feature version supplied by --feature flag. If the feature is not known or the version not yet defined, we throw an error.

Examples :
bin/kafka-feature feature-dependencies --feature transaction.version=2
transaction.version=2 requires:
metadata.version=4 (3.3-IV0) (listing any other version dependencies)

bin/kafka-feature feature-dependencies --feature metadata.version=17
metadata.version=17 (3.7-IV2) has no dependencies

Still seeing an issue with Scala 2.12 :(

Discussed on https://issues.apache.org/jira/browse/KAFKA-17617 that we will remove java 8 and Scala 2.12 anyway so I will merge.
