Implement bundle-info command

The bundle-info command shows detailed data related to a specified
bundle. Among the data currently displayed it includes:
- If the bundle is installed or not
- If the bundle is experimental or not
- If the bundle is installed, it shows if there is an existing update
for the bundle
- The latest available version of the bundle
- The size of the bundle and all its dependencies
- The size needed in disk to install a bundle if not installed

This commit also adds the following command flags:
--version: so a user can display information for a bundle in a
specific version, not only the current version.
--includes: this flag can be used to show all optional and required
bundles that are directly and indirectly included by the specified
bundle.
--files: this flag can be used to show all files that are part of a
given bundle.

All flags can be combined to show specific data.

This is the first of a series of PRs to implement the bundle-info
features referred to at clearlinux#461.
