[ROADMAP] HPC support

[germa89]

Context

We had already several PRs aiming to improve HPC support on PyMAPDL and PyMAPDL behaviour on HPC platforms:

• feat: Supporting SLURM env vars for launching MAPDL configuration #2754 [Behavioural] Allows to take advantage of SLURM env vars to setup MAPDL instance CPUs, RAM, etc,
• feat: support for launching an MAPDL instance in an SLURM HPC cluster #3497 [Support] Allows launching MAPDL instances as SLURM jobs from the entry node and connect to them.
• feat: adding support to launch MAPDL on remote HPC clusters #3713 [Support] Allows launching MAPDL instances in remote machines using ssh on SLURM HPC clusters.

Future work

• Detach remote ssh session from cluster. We should be able to launch MAPDL instances on remote machines without SLURM scheduler.
• Checks if
  • run_location exists.

Closed in favour of #3467 which is more complete.
