feat(import), prompt available paths from imported components to dependents

[davidfirst]

The flag --dependents of bit import brings all the components linked from the workspace components to the specified component (target). In many cases it's not needed and the user is interested in a specific path from the workspace to the component.
This PR makes the following changes:

• if it found 10 paths or less, it shows a multi-select prompt with available paths.
• if it found more than 10 paths, it prompts the first level only (workspace-components) and once selected, it shows the next level only until it reaches the specified component (target).
• once the paths are selected by the user, it shows a prompt with the components that should be imported for the selected paths. The user can confirm or abort.
• the --dependents-dry-run is deprecated. Now it's the default. It always asks for confirmation before bringing in the dependents.
• the --dependents-through flag is renamed to --dependents-via.
• a new flag --silent is introduced to avoid all prompts of --dependents and --dependents-via

Example with less than 10 paths:
