Description

You will implement a task whose goal will be to solve any inconsistencies that could occur between the `mailbox` table and the `mailboxPath` table in Cassandra. You need to solve the following issues :

• If the mailboxPath exists but not the mailbox => create the corresponding mailbox
• If the mailbox exists but not the mailboxPath => remove the mailbox (dangling mailbox that probably didn't get correctly removed)
• If mailbox has id1/path1 and id2/path2 but mailboxPath only have id1/path1 => log an error (GhostMailbox issue)

You can take a look at the similar work that has been done with alias mappings.

You will then expose the task for Cassandra guice products by reusing the `/maiboxes` route, you will implement the new following `TaskRegistration` :

POST /mailboxes?task=solveInconsistencies

You need to implement as well the proper tests and documentation for it as well.
