Generates a list of salt://<formula>/defaults.(json|yaml) files
and fetches them from the Salt master.
Returns first defaults file as python dict.

defaults.get is used much like pillar.get except that it will read
a default value for a pillar from defaults.json or defaults.yaml
files that are stored in the root of a salt formula.
CLI Example:
.. code-block:: bash
salt '*' defaults.get core:users:root
The defaults is computed from pillar key. The first entry is considered as
the formula namespace.
For example, querying ``core:users:root`` will try to load
``salt://core/defaults.yaml`` and ``salt://core/defaults.json``.

defaults.merge
Allows deep merging of dicts in formulas.
merge_lists : False
If True, it will also merge lists instead of replace their items.
in_place : True
If True, it will merge into dest dict,
if not it will make a new copy from that dict and return it.
CLI Example:
.. code-block:: bash
salt '*' default.merge a=b d=e
It is more typical to use this in a templating language in formulas,
instead of directly on the command-line.

defaults.deepcopy
Allows deep copy of objects in formulas.
By default, Python does not copy objects,
it creates bindings between a target and an object.
It is more typical to use this in a templating language in formulas,
instead of directly on the command-line.

defaults.update
Allows to set defaults for group of data set e.g. group for nodes.
This function is a combination of defaults.merge
and defaults.deepcopy to avoid redundant in jinja.
Example:
.. code-block:: yaml
group01:
defaults:
enabled: True
extra:
- test
- stage
nodes:
host01:
index: foo
upstream: bar
host02:
index: foo2
upstream: bar2
.. code-block:: jinja
{% do salt['defaults.update'](group01.nodes, group01.defaults) %}
Each node will look like the following:
.. code-block:: yaml
host01:
enabled: True
index: foo
upstream: bar
extra:
- test
- stage
merge_lists : True
If True, it will also merge lists instead of replace their items.
in_place : True
If True, it will merge into dest dict.
if not it will make a new copy from that dict and return it.

instead of directly on the command-line.
