HDDS-12042. Fix capacity count for cluster capacity card.

Please describe your PR in detail:

• In the new vs old UI we have a discrepancy in the details of the cluster capacity card.

• Mismatch between the Capacity report percentage:

  • In the new UI we are calculating the percentage for the Overview page storage guage chart by choosing the floor value.
  • In the old UI this is done as the rounded value.
  • We are changing the new UI to use the rounded value instead of floor.

• Mismatch between the Pre-allocated size:

  • In the new UI we are making use of the committed field from the storage report response.
  • In the old UI we are not passing this value to StorageBar component, hence it is picking default value of 0.
  • We should change the old UI to make use of the committed size.
