• Deprecation: Keys should not be managed at the Index level but at the Client level

  All methods Index.(list|get|add|update)_api_keys() are now
  deprecated. If you already have keys on the Index, it would be best
  to delete them and regenerate new keys with client, adding the indexes
  restriction.

  Example:

  client.add_api_key({
      'acl': 'search',
      'indexes': 'my_index_name',
  })

• Feat: Let you define all API keys capabilities in one map for update_api_key and add_api_key

  Example:

  client.add_api_key({
      'acl': ['search'],
      'validity': 300,
      'maxQueriesPerIPPerHour': 100,
      'maxHitsPerQuery': 20,
      'indexes': ['dev_*'],
      'referers': ['algolia.com/*'],
      'queryParameters': 'typoTolerance=strict&ignorePlurals=false',
      'description': 'Limited search only API key for algolia.com'
  })

  instead of

  client.add_api_key(['search'], 300, 100, 20, ['dev_*'])

• Fix: Adding a rule with an empty ID failed silently, it will now raise an exception

• Fix: Index.get_objects requires an array for attributes_to_retrieve
  strings could be passed before but it would fail silently every time
  See #299

• Fix: When browsing, ensure cursor is passed in the body
  Cursor can become so long that the generated URL fails (error HTTP 414).

• Chore: Add Python version to the UserAgent
