Add options to filter lists_mergeby (#4058)

Browse source 
* Update filter lists_mergeby #4057

* Added options 'recursive' and 'list_merge'. The functionality of the
  added options is the same as in the filter 'combine'.
* Allow the user to do [list1, list2, ...]|lists_mergeby('index')
* Use the function merge_hash from ansible.utils.vars

* Add merge_hash_wrapper to test Ansible version

* Enable Ansible 2.9 and lower versions with default options of
  lists_mergeby only.
* Non-default options of lists_mergeby trigger error in 2.9 and lower
  versions.
* Update messages and tests.

* Fix tests.

* Use LooseVersion instead of SpecifierSet.

* Update docs 'Filter Guide' section 'Merging lists of dictionaries'.

* Added changelog fragment.

* Update changelogs/fragments/4058-lists_mergeby-add-parameters.yml
