Cloud Foundry Route Lookup Plugin

This is a Cloud Foundry CLI plugin to quickly identify applications, a given route is pointing to.
Note this will only show applications in organizations and spaces, that the logged-in user has permissions to view.
The plugin also supports targeting to the organization and space of the applications, a given route is pointing to.

Usage Sample

$ cf lookup-route <my.example.com>
Bound to:
Organization: <org> (<org_guid>)
Space       : <space> (<space_guid>)
App         : <app1> (<app_guid_1>)
App         : <app2> (<app_guid_2>)

Why Is This PR Valuable?

• There are multiple scenarios, where users wish to quickly search for all the apps bound to a certain route, target the corresponding org and space of the apps to perform some changes there (e.g. list or add users).
• This plugin uses CF API v3.

TO DOs

• The plugin's name field in repo-index.yml matches the Name field in the plugin's plugin.PluginMetadata section
• The plugin's url field in repo-index.yml contains the same version from the version field
