Curator-opensearch

------------------------

**New Features**

* Configuration and Action file schema validation. Requested in 674
(untergeek)
* Alias filtertype! With this filter, you can select indices based on whether
they are part of an alias. Merged in 748 (untergeek)
* Count filtertype! With this filter, you can now configure Curator to only
keep the most recent `n` indices (or snapshots!). Merged in 749
(untergeek)
* Experimental! Use environment variables in your YAML configuration files.
This was a popular request, 697. (untergeek)

**General**

* New requirement! ``voluptuous`` Python schema validation module
* Requirement version bump: Now requires ``elasticsearch-py`` 2.4.0

**Bug Fixes**

* ``delete_aliases`` option in ``close`` action no longer results in an error
if not all selected indices have an alias. Add test to confirm expected
behavior. Reported in 736 (untergeek)

**Documentation**

* Add information to FAQ regarding indices created before Elasticsearch 1.4.
Merged in 747

----------------------

**Bug Fixes**

* Update old calls used with ES 1.x to reflect changes in 2.x+. This was
necessary to work with Elasticsearch 5.0.0-alpha5.
Fixed in 728 (untergeek)

**Doc Fixes**

* Add section detailing that the value of a ``value`` filter element should
be encapsulated in single quotes. Reported in 726. (untergeek)

---------------------

**Bug Fixes**

* Fix incorrect variable name for AWS Region reported in 679 (basex)
* Fix ``filter_by_space()`` to not fail when index age metadata is not
present. Indices without the appropriate age metadata will instead be
excluded, with a debug-level message. Reported in 724 (untergeek)

**Doc Fixes**

* Fix documentation for the space filter and the source filter element.

---------------------

**Bug Fixes**

* Fix incorrect variable name in Allocation action. 706 (lukewaite)
* Incorrect error message in ``create_snapshot_body`` reported in 711
(untergeek)
* Test for empty index list object should happen in action initialization for
snapshot action. Discovered in 711. (untergeek)

**Doc Fixes**

* Add menus to asciidoc chapters 704 (untergeek)
* Add pyyaml dependency 710 (dtrv)

--------------------

**General**

* 4.0.2 didn't work for ``pip`` installs due to an omission in the
MANIFEST.in file. This came up during release testing, but before the
release was fully published. As the release was never fully published, this
should not have actually affected anyone.

**Bug Fixes**

* These are the same as 4.0.2, but it was never fully released.
* All default settings are now values returned from functions instead of
constants. This was resulting in settings getting stomped on. New test
addresses the original complaint. This removes the need for ``deepcopy``.
See issue 687 (untergeek)
* Fix ``host`` vs. ``hosts`` issue in ``get_client()`` rather than the
non-functional function in ``repomgrcli.py``.
* Update versions being tested.
* Community contributed doc fixes.
* Reduced logging verbosity by making most messages debug level. 684
(untergeek)
* Fixed log whitelist behavior (and switched to blacklisting instead).
Default behavior will now filter traffic from the ``elasticsearch`` and
``urllib3`` modules.
* Fix Travis CI testing to accept some skipped tests, as needed. 695
(untergeek)
* Fix missing empty index test in snapshot action. 682 (sherzberg)
