[Bug 1859412] [NEW] security: set default umask for service to 0027

[James Page]

Public bug reported:

OpenStack services have no way to specify the permissions on log files
created; standards such as CIS set a default umask of 0027 however that
is not applied to units running under systemd.

This means that log files (and any other files or directories created by
a daemon) will have global read permissions by default.

As the systemd unit files are templated, we can update this fairly
easily for openstack services by adding the UMask=0027 directive to the
core template.
