Wait until the longterm datacheck file is created to make the link

[marialainez]

Currently, autocloser is trying to make the symlink of the file right after the cherenkov_transparency script is launched, and it fails because the file has not yet been created. I put long times to wait for the job completion because nowadays there are many jobs running in the cluster, and many of them stay in PENDING status for a long time until they start running.

EDIT:

The first time closer runs it will go through the else, and wait to see if all the jobs are finished (until the hour), if so, the flag is created. If it is not closed after that hour, there is no nightfinished flag. Then closer runs again, first it checks that the longterm file exists, if it does it goes to the job completion check directly and tries to close again.
