Fix(slurm): resolve KeyError control_host in slurmdbd config templates

[SwarnaBharathiMantena]

Description

This PR resolves a template rendering bug in the SchedMD Slurm v6 controller startup setup. During cluster provisioning, the Slurm Database Daemon setup failed to compile slurmdbd.conf because the {control_host} formatting key was missing from the configuration options context, causing the automated cluster deployment tests to abort.

Root Cause

In modules/scheduler/schedmd-slurm-gcp-v6-controller/files/conf.py, the install_slurmdbd_conf function attempts to format the slurmdbd_conf_tpl template using .format(**conf_options). Since the template contains the {control_host} placeholder, but "control_host" was omitted from the local conf_options dictionary, a Python KeyError: 'control_host' was thrown.

This error halted the setup scripts midway, preventing slurmctld from starting and causing overall integration tests (such as htc-slurm-v6) to fail under Cloud Build.

Fix Applied

Added the "control_host": lkp.control_host key-value pair to the local conf_options dictionary inside the install_slurmdbd_conf function in conf.py. This ensures that all required placeholders in slurmdbd_conf_tpl render successfully on controller bootstrap.
