Enabling softQuota while creating blobstore

[bpoorva]

blobStores:

• name: xxxx # required
  type: file # optional (defaults: file)
  path: xxxx
  softQuota:
  type: spaceRemainingQuota
  limit: 1024

This should create blobstore with softQuota, however it doesnot. And the result is same as -
blobStores:

• name: xxxx # required
  type: file # optional (defaults: file)
  path: xxxx
