Describe the bug
A clear and concise description of what the bug is:
Would like to disable the autosync of labels since it overrides our labels we set.

To Reproduce
Steps to reproduce the behavior:
Have 2 azurekeyvaultsecrets pointing to the same secret but with different metadata.labels.name.
We noticed this when we got to add an annotation and added the secret to our repo and the annotations gets overriden by the azurekeyvaultsecret.

Expected behavior
A clear and concise description of what you expected to happen:
Not override existing labels, only append.
Maybe a feature flag in the controller to enable/disable this option.

Logs
If applicable, add logs to help explain your problem.
N/A

Additional context
Using ArgoCD so we autosync the change but the controller keep overriding.
Our use case is to have autoreload with stakater/Reloader and have this annotated on the secret object.
Great plugin to use together with azure keyvault, 10/10 would use again

Thanks for reporting this @tehho. Just to clarify, It is the k8s secret's labels and/or annotations that gets overwritten by the the akv2k8s controller when syncing the AzureKeyVaultSecrets? This is either way not a desired outcome.

If you have any suggestions of the implementation/design, contribution to this would be much appreciated 😄
