Release prep for 8.0.14

[untergeek]

Announcement

• A long awaited feature has been added, stealthily. It's fully in the documentation, but I do
  not yet plan to make a big announcement about it. In actions that search through indices, you
  can now specify a search_pattern to limit the number of indices that will be filtered. If
  no search pattern is specified, the behavior will be the same as it ever was: it will search
  through _all indices. The actions that support this option are: allocation, close,
  cold2frozen, delete_indices, forcemerge, index_settings, open, replicas, shrink, and snapshot.

Bugfix

• A mixup with naming conventions from the PII redacter tool got in the way of the cold2frozen
  action completing properly.

Changes

• Version bump: es_client==8.13.0
  • With the version bump to es_client comes a necessary change to calls to create a
    repository. In Expand snapshot repository types elasticsearch-specification#2255 it became
    clear that using type and settings as it has been was insufficient for repository
    settings, so we go back to using a request body as in older times. This change affects
    esrepomgr in one place, and otherwise only in snapshot/restore testing.
• Added the curator.helpers.getters.meta_getter to reduce near duplicate functions.
• Changed curator.helpers.getters.get_indices to use the _cat API to pull indices. The primary
  driver for this is that it avoids pulling in the full mapping and index settings when all we
  really need to return is a list of index names. This should help keep memory from ballooning
  quite as much. The function also now allows for a search_pattern kwarg to search only for
  indices matching a pattern. This will also potentially make the initial index return list much
  smaller, and the list of indices needing to be filtered that much smaller.
• Tests were added to ensure that the changes for get_indices work everywhere.
• Tests were added to ensure that the new search_pattern did not break anything, and does
  behave as expected.
