* Fix unbound method call for JSONEncoder
The way it is currently it will lead to unbound method error
```python
In [1]: import json
In [2]: json.JSONEncoder.default('object_here')
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-2-872fdacfda50> in <module>()
----> 1 json.JSONEncoder.default('object_here')
TypeError: unbound method default() must be called with JSONEncoder instance as first argument (got str instance instead)
```
But what is really wanted is to let the json module to raise the "is not serializable error" which demands a bounded instance of `JSONEncoder()`
```python
In [3]: json.JSONEncoder().default('object_here')
---------------------------------------------------------------------------
TypeError: 'object_here' is not JSON serializable
```
BTW: I think it would try to call `.to_json` of object before raising as it is a common pattern.
* Calling JSONEncoder bounded `default` method using super()

Searching the DEFAULT_ROLES_PATH and the roles basedir should come
before this, and it has been a long standing oversight.

* Add tests for the mount module
* Switch from unmounted to absent...
the code for mounting always modifies fstab so we need to always modify
fstab to cleanup as well.
* Fix comments and copyright
6eefc11c converted task.loop_control into an object, but while the other
callers were updated to use .loop_var instead of .get('loop_var'), this
site was overlooked.
This can be reproduced by including with loop_control a file that does
set_fact; a simple regression test along these lines is included.

The cherry-pick allows module parameters to convert int to float, fixing
bugs where a float type is required. However, it used types from the
six library for python3 compatibility as well. Since we don't have
six in 2.1.0 this was buggy. Merging the unittests for the problem
here: adc158a499 made this buggy behaviour
apparent.
A parameter of type int should accept int and string, but not float.
A parameter of type float should accept float, int, and string.
Also reset the arguments in another test so that it runs cleanly. This
agrees with what all the other tests are doing.
When using hostvars to get extra connection-specific vars for connection
plugins, use this raw lookup to avoid prematurely templating all of the
hostvar data (triggering unnecessary lookups).

(cherry picked from commit ac5ddf4aa092e12f9e1c85c6b74aa30b7ef0a382)
Copying the TaskInclude task (which is the parent) before loading the blocks
makes the code much more simple and clean, and fixes a bug introduced during
the performance improvement changes (and specifically the change which moved
things to a single-parent model).
