move and delete books manually

[elfkuzco]

Rationale

This PR adds functionality to move, recover and delete books from the API/UI.

Changes

• add endpoints to delete, move and recover book
• move quarantine and staging related warehouse env vars from mill to common context as they are now used by the API layer too
• enhance get_book_or_none function to allow for passing params for filtering instead of having if...else checks for attributes
• add db functions to move, recover and delete book
• previously, the shuttle delete_files logic set the book has_error if deletion failed. This doesn't seem correct as the book does not necessarily have an error. Instead, in addition to logging the exception message, set the needs_file_operation to False
• remove the has_error flag from filters to get_next_book_to_delete as we want to now delete books that have errors too
• add UI buttons to move, recover and delete book
• only include quarantine, staging and/or prod books in library.xml generation (filter added in DB query get_latest_books_for_collection)

This closes #143
