provide explicit paths to sbatch squeue and scancel in the strudel config generated for generic clusters

Slurmbranch4

a bunch of fixes

Slurmbranch3

tell sssd to ignore munge and slurm accounts in ldap. They shouldn't be there anyway since these are system users, not user accounts

point the slurmdbd at localhost for mysql rather than refering to the hostname. Saves having to configure firewalls and mysql for network access. We may later this latter if we want to move the sql server somewhere else

fix up the NFS related tasks, so that the server definitly restarts after the exports are written and the mounting of filesystems on clients is correct

fixed templates

Fixed syncExport
