Add cancel task for v0.30.0

[bidoubiwa]

Breaking changes

• Changed TasksQuery structure to TasksSearchQuery when building the query parameters for a get_tasks call.

before:

  let mut query = TasksQuery::new(&client)
      .with_index_uids(["movies"])
      .execute()

after:

  let mut query = TasksSearchQuery::new(&client)
      .with_index_uids(["movies"])
      .execute()

• attributes of TasksSearchQuery are now private. Meaning you cannot do this anymore:

  let mut query = TasksSearchQuery::new(&client);
  query.limit = 10; // Does not work anymore, limit is private

Enhancement

• New tasksCancelQuery to structure to build the filters to cancel tasks.

Todo
