History rewrite: handle Gitaly errors

What does this MR do and why?

Contributes to #483085 (closed)

Problem

There is no handling for Gitaly related errors. Because of that RewriteHistoryService will raise an error instead of returning a ServiceResponse object.

Solution

• Add Gitaly error handling for #rewrite_history to RepositoryCleaner class
• Use RepositoryCleaner in RewriteHistoryService instead of directly calling Gitaly client.
• Add tests for Gitaly error handling.
