Update git submodules

  • Update extensions/CirrusSearch from branch 'wmf/1.29.0-wmf.11'
    • Explicitly use BM25 as default for wmf_defaults similarity profile

      The 2.x -> 5.x conversion has some uncertainties aroung similarity profiles and the 'default' similarity. To make things explicit and easy to understand force BM25 as the type for wmf_defaults.

      Specifically fields in 2.x that specify similarity as default will report in 5.x that their similarity is classic. It appears though that the actual search will still use BM25 (tested in 5.1.2, see https://github.com/elastic/elasticsearch-migration/issues/103#issuecomment-279546227) To ensure that _mapping doesn't report something wrong, and that there arn't other lingering, undetected, bugs with this conversion, we explicitly name BM25 as the similarity config.

      Change-Id: I32ddeeb18ac93623ff16b3f9b895c925394e3944 (cherry picked from commit 22edc18abdb2f31d1fac76fdf59c4770f75266b9)
