Previously the timeout for deleting chart releases was 300s and
not configurable, this patchset makes it so via a new
`delete.timeout` property in the `armada/Chart/v1` schema.
Helm releases deleted which do not correspond to documents in this
schema still do not use a configurable timeout. Those will be
considered separately.
This also includes a minor logging fix.
