Use existing PV for VLSingle storage

[bo0tzz]

Currently, VLSingle spec.storage takes a PersistentVolumeClaimSpec. This means there is no clear way to declare a volume separately outside the CRD.

[AndrewChubatiuk]

have you tried VLSIngle's spec.volumes and spec.volumeMounts

[bo0tzz]

I have not - but if that's the canonical way to specify an existing volume, it should probably be described in the docs.

It'd be great to have an examples for both VMSingle and VLSingle configurations. Because currently, it requires non-trivial steps to mount exist PVC.

Hey @AndrewChubatiuk, would you mind adding a few examples?

Closing as resolved. The example was added in #1488 and is now available in the documentation: https://docs.victoriametrics.com/operator/resources/vlsingle/#vlsingle-with-existing-volume

Feel free to reopen if any questions remain.
