Embed bbolt command as etcdutl subcommand

[serathius]

What would you like to be added?

Embed bbolt command as etcdutl subcommand. Options for names:

• etcdutl bbolt
• etcdutl db

Why is this needed?

Improves user experience

• easier access
• etcd documentation could start recommending using bbolt commands without requiring users to learn bbolt

Downsides:

• Might require rewrite to make commands compatible
• Binds to command interface in other project

@serathius I would like to take this feature on. I am a new contributor to this codebase, so I have a couple of quick questions:

• Is bbolt the default underlying data structure used for the key-value store? I am trying to understand why we need to explicitly specify bbolt in addition to improving the user experience.
  EDIT: After reading through the bbolt docs, I think I might have a better understanding for this task. Is the goal for this feature to be able to execute bbolt commands through etcdutl subcommand?
• What is the expected functionality when a user types etcdutl bbolt .. ?
  Thanks
