feat(crd): scripts to help migrating to new CRDs (#73)

Browse source 
The CRDs have changed from being under openebs.io to zfs.openebs.io. 

The scripts in this commit and the following steps will help users migrate existing CRDs to new CRDs and clean up older CRDs. 

# upgrade to new CRD
1. apply the crd yaml
    `$ kubectl apply -f upgrade/crd.yaml`

2. run upgrade.sh
    `$ upgrade/upgrade.sh`

3. upgrade the driver to v0.6
    `$ kubectl apply -f https://github.com/openebs/zfs-localpv/blob/v0.6.x/deploy/zfs-operator.yaml`

4. if everything looks good run the cleanup.sh, it will clean old CRs and delete the CRD
    `$ upgrade/cleanup.sh`
