resource configuration through a ~/.mintpyrc file

[falkamelung]

Description of the desired feature

Currently it is not practical to use the same custom template file (e.g. FernandinaSenD128.template) on different platforms (on a HPC system and on your laptop) as it contains these system-related parameters:

mintpy.compute.maxMemory = auto #[float > 0.0], auto for 4, max memory to allocate in GB
mintpy.compute.numWorker = auto #[int > 1 / all / num%], auto for 4 (local) or 40 (slurm / pbs / lsf), num of workers
mintpy.plot.maxMemory = auto  #[float], auto for 4, max memory used by one call of view.py for plotting.

It would be nice to have the option to configure these parameters for each platform individually through an ~/mintpyrc in the home directory. That looks to be easy to implement: when filling parameters with the default values from defaults/smallbaselineApp_auto.cfg it should check for a ~/mintpyrc or ~/smallbaselineApprc.

Would that be of interest? If so, please add suggestions if you have (including naming preference).

Are you willing to help implement and maintain this feature?

I like this ~/.mintpyrc file idea, and it won't affect any existing functionalities. You are more than welcome to implement it @falkamelung.

For the implementation, I would think it should be: whenever the template option value is auto, which means users have not modified it (as one could have specified a custom value, which by incidence is the default value), the code should check the existence of the ~/.mintpyrc file and use it instead of the defaults/smallbaseline_auto.cfg file. This can be done within the utils.utils1.check_template_auto_value().
