Print /COM to python console

[germa89]

I feel it could be useful to have the /COM commands printing also the python console.

I'm aware this might not be the greatest feature ever and it will not be used that much, but I feel it can be useful.
For example, for the ds.dat files which are converted from Mechanical, it is useful to print this /COM output, so we know for example in which stage of the execution we are in, without having to add manually prints.

I coded this feature to be disabled by default in Mapdl execution but it will be default in the converted (I guess MAPDL people will appreciate having this kind of input).
This feature can be activated at any moment by editing the appropriate property: mapdl.print_com.
See unit test for an example.

@akaszynski coverage can be addictive (95.23%!!)

Coverage is absolutely addictive; well done getting it past 90%.

I feel that we should have another PR to just improve command coverage by reusing MAPDL regression tests. Talk to their testing team.

Good idea adding the option to print.

LGTM.
