Configure ASM mirroring for OCR and Voting Disk

1.Create another disk group OCR_VOTE_NORM with three asm disks with normal redundancy.

2.Replaced the current OCR_VOTE disk group (external redundancy) with OCR_VOTE_NORM
./crsctl replace votedisk +OCR_VOTE_NORM

3. Added OCR_VOTE_NORM disk group to OCR
./ocrconfig -add +OCR_VOTE_NORM

4. There are two copies of OCR files and three copies of Voting disks.
