[mysqldump] Upload to GoogleStorageBucket should not do deletion

[elwood218]

Describe the bug
At the moment the script for uploading to GoogleStorageBucket is using the "-d" option so the files in the bucket get deleted! Instead this should be done by the Lifycycle management of the Google Storage Bucket.

Version of Helm and Kubernetes:
not relevant

Helm Version:
not relevant

Kubernetes Version:

not relevant

Which version of the chart:
4.0.2

What happened:
Files get deleted by rsync command.

What you expected to happen:
Files should not get deleted or at least this should be editable.
Then I could use "housekeeping" that my PVC will not grow size and also use the GCP "lifecycle" to manage how many backup files I want to keep in the Google Storage Bucket.

How to reproduce it (as minimally and precisely as possible):

<~--
This could be something like:

values.yaml (only put values which differ from the defaults)

key: value

helm install my-release {{ .GitHubOrg }}/name-of-chart --version version --values values.yaml

-->

Anything else we need to know:
