It leaves certain ceph mentions in globals.yml.j2 as it needs
syncing with kolla-ansible contents anyways
(these are all comments).

Commit d8ee0fa0 introduced the variable
kolla_enable_keystone without setting a default value and used it to
check whether to template and provide keystone.conf to kolla-ansible,
unlike the extended keystone configuration which was always copied. This
resulted in non-intuitive behaviour if kolla_enable_keystone wasn't
explicitly set by the operator.

This commit sets kolla_enable_keystone to true by default, which matches
the default in kolla-ansible, and uses it instead of hardcoded true
values.

It is now possible to configure custom inputs for fluentd by placing files in
etc/kayobe/kolla/config/fluentd/input/ in the kayobe configuration.

InfluxDB config file merging isn't supported in Kolla-Ansible because
it uses 'nested sections' which aren't supported by merge_configs. If
no override file is specified, Kayobe will write out an empty config
file which will then be used as the InfluxDB config file, breaking
InfluxDB. To prevent that happening this change removes the extra
config in Kayobe. It also fixes the directory to which the 'glob'
collected config is copied to, as Kolla-Ansible doesn't look for
Influxdb config files in the influxdb folder.
