Checking connectivity for each host should be carry out only before running the experiment

Hi in Autosubmit 3.13.0b, for changing status of a given job, checking the connectivity with platforms used may be skipped since at this point users just want to change status of a job, not run. since Nord3 is down I cannot change the status even if the job I want to run will execute in other platform than Nord3 ( that is currently down )

autosubmit setstatus a36j -ft "SYNCHRONIZE" -t READY -s -nt -np Preparing .lock file to avoid multiple instances with same expid.

Checking configuration files...
expdef_a36j.conf OK
platforms_a36j.conf OK
jobs_a36j.conf OK
wrappers OK
autosubmit_a36j.conf OK
Configuration files OK

Creating jobs...
Loading JobList
Adding dependencies...
Removing redundant dependencies...
Checking the connection to all platforms in use
[local] Connection successfull to host localhost
[ERROR] Trace: [nord3] connection failed for host: nord1.bsc.es
 [CRITICAL] Unhandled error: If you see this message, please report it in Autosubmit's GitLab project

ideally checking connectivity is a cool idea before starting running the experiment, however for all the other commands may add overhead.
