The default behavior of divingbell-perm is to fail when trying to assign
permissions to non-existent files.
This change adds an option to values.yaml to skip any missing files and
proceed with the rest of the assignments.
conf:
perm:
ignore_missing: true # default is false
This may be useful in cases where files will never exist on a node, or
cases where the file does not exist yet, but will exist later. Note that
with this option enabled, a run in which files are skipped is considered
successful, so the rerun_policy and rerun_interval will determine if and
when another attempt will be made.
