[Enabler] [zos_data_set] Add back default record format, new logic to handle default FB

[ddimatos]

Enabler description

As a result of the later ansible versions such as 2.14 the code was updated to move the module default record format of FB. It does not make good sense to not have a default as one who does not know z/OS it could be helpful, the problem is that with such a default and the current modules design, a default record format FB will break VSAM type data sets.

Logic has been added to remove the defaults when needed but also to clean up any dangling values when batch and non-batch options are set as it can be confusing to see values for non-batch when batch is used.

Here is what a successful batch result should look like as to not confuse any one looking at log dumps , best to None out the values we don't use:
