slurm.conf contains malformed (trimmed) templates

[tom91136]

I saw a few instances where the templated config end up looking like:

# many more normal lines
SlurmctldHost=mgmt.staging.local#SlurmctldHost=
# many more normal lines
SlurmctldParameters=enable_configlessReturnToService=2

Which corresponds to trimmed blocks:

ansible-role-openhpc/templates/slurm.conf.j2

Line 186 in a599130

{% if openhpc_slurm_configless %}SlurmctldParameters=enable_configless{% endif %}

This may have occurred for other templates as well, but I'll have to check.
The documentation seems to suggest that this trimming of the template is the default but behaviour can be changed: ansible/ansible#22531
