What's in this PR?

Created ObjectMetaWithNameAndAnnotations and ObjectMetaWithName to allow creation of objects with a deterministic name.
Use ObjectMetaWithNameAndAnnotations instead of ObjectMetaWithGeneratedNameAndAnnotations When creating a PVC.
Removed the hyphen at the end of brokerStorageTemplate since there isn't going to be a generated suffix.

Why?

When using storage classes that span multiple Kubernetes clusters which use the PVC name to identify the volume that is referenced by the PersistentVolumeClaim or VolumeClaimTemplates, the PVC must have a deterministic name so it could be referenced on all the Kubernetes clusters that will reference it.

Additional notes

We have tested the the code yesterday, it works but we have other issues that prevent the scenario we are aiming for to succeed.
Would love your thoughts about it in the meanwhile.
Also, I make this change optional by adding a flag to StorageConfig:

type StorageConfig struct {
	MountPath string                                                     `json:"mountPath"`
        IsGlobal      bool                                                       `json:"isGlobal"`
	PvcSpec    *corev1.PersistentVolumeClaimSpec `json:"pvcSpec"`
}

Hi @zaidenwerg please look my answer here how can you create manually your own PV and PVC for the operator.

@zaidenwerg could you describe the use case global PVC names would be needed across multiple Kubernetes clusters for Kafka?
