Tags should retain case, and should not be snake cased.
Easiest way to do this is to snake before converting tag
list as while that affects the keys of the boto3 tag lists,
it doesn't affect the values. Need to use `tag_value_key_name`
and `tag_name_key_name` following recent change to
`boto3_tag_list_to_ansible_dict`, which used to handle both
`key`/`Key` and `value`/`Value`
Fix converts commit_timeout to string as
Elementree.SubElement requires text as string.

We have a protection against a user setting use_default_subnetpool in
their playbook - but then we sure do pass the kwarg anyway. Maybe let's
not do that.
With newer versions of ansible, module arguments are assumed to
be strings unless otherwise specified. Our 'facts' argument is
expected to be a dictionary, so tell ansible that.
Without this, the argument will arrive as a string and be written
to the facter file inside string quotes. Facter will produce the
following error:
undefined method `each' for #<String:0x000000016ee640>
This was originally fixed and found in the Ansible Puppet role which
is maintained by the OpenStack infrastructure team.

On Python3 and Python2 use pickle slightly differently so we need to be
explicit about some things.
If pickles could be shared between python2 and python3, as in
ansible-connection and the pickle cache, we need to specify the protocol
to use when dumping and the encoding to use for byte strings when
loading.
The dumping protocol needs to be no higher than 2 as python-2 only
supports up to protocol 2. The encoding should usually be 'bytes' so
that python2 str type becomes python3 bytes type. However, doing this
means that we must make sure that the objects being serialized properly
make their strings into text strings except when they're supposed to be
bytes. If strings are improperly byte strings, they may cause
tracebacks on the receiving end
Fix for persistent connection plugin on Python3. Note that fixes are also needed to each terminal plugin. This PR only fixes the ios terminal (as proof that this approach is workable.) Future PRs can address the other terminal types.
* On Python3, pickle needs to work with byte strings, not text strings.
* Set the pickle protocol version to 0 because we're using a pty to feed data to the connection plugin. A pty can't have control characters. So we have to send ascii only. That means
only using protocol=0 for pickling the data.
* ansible-connection isn't being used with py3 in the bug but it needs
several changes to work with python3.
* In python3, closing the pty too early causes no data to be sent. So
leave stdin open until after we finish with the ansible-connection
process.
* Fix typo using traceback.format_exc()
* Cleanup unnecessary StringIO, BytesIO, and to_bytes calls
* Modify the network_cli and terminal plugins for py3 compat. Lots of mixing of text and byte strings that needs to be straightened out to be compatible with python3
* Documentation for the bytes<=>text strategy for terminal plugins

Template can take a directory as the destination. When that's the case,

not when it was specified on its own. This change fixes that.
Fixes#24413
For playbook base objects, when dumping attributes via dump_attrs() an
attribute like loop_control is a class. Using the default serialization
for these is slow and consumes a lot of memory. Since LoopControl is also
based on the Base class, we can use serialize() instead and save a lot of
resources.
This also adds a from_attrs() complimentary method to nicely turn the
dumped attrs back into proper field attributes.

CVE-2017-7481
Lookup returns wrap the result in unsafe, however when used through the
standard templar engine, this does not result in the jinja2 environment being
marked as unsafe as a whole. This means the lookup result looses the unsafe
protection and may become simple unicode strings, which can result in bad
things being re-templated.
This also adds a global lookup param and cfg options for lookups to allow
unsafe returns, so users can force the previous (insecure) behavior.
Output of `yum check-update` can contain lines with long package names and long
repository label names, which will be broken into multiple lines, which need to
be sanitized. The solution to this has been fixed and refactored in 2.3 in form
of parse_check_update(), but it still contains subtle bug, which makes such
multi-lines invisible to later logic (such packages aren't included in
parse_check_update()) output. The problem is caused by using '\1' in re.sub(),
instead of proper r'\1', which literally puts unicode symbol \1 into resulting
output.
ssh-keyscan isn't very verbose about errors. Give the user whatever

If a bridge does not have a fail mode set, it returns nothing, i.e.

This causes a failure when doing the want vs have compare in plays

This causes issues on the current want vs have comparison in cases

Just after release of 2.0.0 (in 2.0.0.1) we had a change to the API of
callbacks without bumping the API version. We added the playbook to the
arguments passed to the callbacks.
This wasn't in the Tower callback at the time. In order to prevent
breaking that callback we added a temporary hack to inspect the
callback's API to decide if we needed to call it with arguments or not.
We scheduled the hack for removal in January 2017. Since that's now
past, removing the hack.
Change signed off by matburt on the Tower side.

Resource pools are retrieved from VSphere regardless of the state of the `resource_pool` parameter. During this process, each retrieved Resource Pool is checked for the `parent` attribute, and if it exists, the currently-scoped parent object is compared against the Resource Pool's parent object. The method doing the check, however, `assert`s that the parent object is not `None`. In some cases, a Resource Pool will have the `parent` attr, but that `parent` object will be `None`, causing the `assert` to fail.
This should avoid that. :-)

* Fix vault reading from stdin (avoid realpath() on non-links)
os.path.realpath() is used to find the target of file paths that
are symlinks so vault operations happen directly on the target.
However, in addition to resolving symlinks, realpath() also returns
a full path. when reading from stdin, vault cli uses '-' as a special
file path so VaultEditor() will replace with stdin.
realpath() was expanding '-' with the CWD to something like
'/home/user/playbooks/-' causing errors like:
ERROR! [Errno 2] No such file or directory: u'/home/user/ansible/-'
Fix is to specialcase '-' to not use realpath()
