[SlurmDbd] Adding a message to make sure that we do not use # in DB Password

[himani2411]

Description of changes

• Fail fast with a message which specifies # is not allowed in slurm dbd configuration files.
• As per https://slurm.schedmd.com/slurmdbd.conf.html

StoragePass
Define the password used to gain access to the database to store the job accounting data. The '#' character is not permitted in a password.

When running manually

sudo ./update_slurm_database_password.sh
Reading password from /opt/slurm/etc/slurm_parallelcluster_slurmdbd.conf
Reading password from AWS Secrets Manager: arn:aws:secretsmanager:ap-south-1:447714826191:secret:AccountingClusterAdminSecre-xImvFgSN8JqP-BXWv1l
You cannot use the # character in the database password as Slurm does not support it with StoragePass configuration paramter in /opt/slurm/etc/slurm_parallelcluster_slurmdbd.conf. You can get more details in https://slurm.schedmd.com/slurmdbd.conf.html

[minor] Better to avoid URLs in error messages because they may change over time, espcieally if they are not under our control. I suggest to simply say something like 'Please, refer to the official documentation from SchedMD for more details.'
