add_separate_group.db_secret

[vladimir4862]

Hello!
I'm not very experienced with Trino configuration, but I do have a bit more experience with Helm charts.
The main question in this PR is determining the correct place to change the file.password-file and file.group-file configurations.

I placed them in a separate folder to keep automatic updates when k8s secrets are updated.
This approach contrasts with using subPath, which does not support automatic file updates within pod volumes.

I was inspired by the issue
So maybe @robertpikmets also whant to look at this.
