Catching MAPDL process output

[germa89]

New features

Several things are done in this PR:

• Added mapdl.launched property. This is True if we have started the mapdl process. It is similar to mapdl.local. However you can have mapdl.local equal to True (mapdl instance running on the same machine) but mapdl.launched equals False because you manually launched. Another PR should follow up to clarify/unify mapdl.local usage.

• Adding support for process checking. Now if we fail to connect to MAPDL, we automatically check the process (subprocess.Popen) output and we raise any error, warning or fatal erros we find.

  try:
      self._multi_connect(timeout=timeout, set_no_abort=set_no_abort)
  except MapdlConnectionError as err:
      self._post_mortem_checks()
      raise err  # Raise original error if we couldn't catch it in post-mortem analysis
  else:
      self._log.debug("Connection established")

• The mapdl process (subprocess.Popen) is now accessible on mapdl._mapdl_process in grpc and corba modes.
• We dont do any checks on corba mode.
• I have also started to deprecate verbose argument in corba and grpc classes.
• Adding unit tests and docs.

Caveats

• The processes are directed to a subprocess.PIPE object. It should have no effect on the normal MAPDL work mode because of the arguments -o supplied (in Windows). Because of this redirection, verbose needs to be deprecated (verbose redirect the output to screen?)
• I'm considering if we should return an object after failing to connect. This object could be either an MAPDL class with some attributes with the error output (for debugging purposes) or an object with this error information

@clatapie please have a look at this PR. I think it is an interesting one!

The ubuntu local test keeps getting stuck on the test_krylov_with_pressure_load test. See #1755

Inteeeresttinggggg...

Last commit just to check if a newly created run fixes the test. Of course it should not... but who knows.
