Return a dictionary that includes all of the information needed to install a repository into a local
Galaxy instance. The dictionary will also contain the recursive list of repository dependencies defined
for the repository, as well as the defined tool dependencies.
This method is called from Galaxy under four scenarios:
1. During the tool shed repository installation process via the tool shed's get_repository_information()
method. In this case both the received repository and repository_metadata will be objects, but
tool_dependencies and repository_dependencies will be None.
2. When getting updates for an installed repository where the updates include newly defined repository
dependency definitions. This scenario is similar to 1. above. The tool shed's get_repository_information()
method is the caller, and both the received repository and repository_metadata will be objects, but
tool_dependencies and repository_dependencies will be None.
3. When a tool shed repository that was uninstalled from a Galaxy instance is being reinstalled with no
updates available. In this case, both repository and repository_metadata will be None, but tool_dependencies
and repository_dependencies will be objects previously retrieved from the tool shed if the repository includes
definitions for them.
4. When a tool shed repository that was uninstalled from a Galaxy instance is being reinstalled with updates
available. In this case, this method is reached via the tool shed's get_updated_repository_information()
method, and both repository and repository_metadata will be objects but tool_dependencies and
repository_dependencies will be None.
