When the Allocation Swift Storage Quota Attribute i.e. "OpenStack Swift Quota in Gigabytes" set to 0 provides unlimited quota to the user.

[Milstein]

• "OpenStack Swift Quota in Gigabytes" value is set to 0.
• RGW interprets 0 as meaning unlimited quota as pointed here.
• It successfully removes the properties | Quota-Bytes while checking using openstack object store account show command.
• We can't set the Quota-Bytes property to 0 or Empty so we need set it to 1 byte that will the minimal we can set to prevent any future cost to the user.

The solution here involves:

• When the attribute OpenStack Swift Quota in Gigabytes is set to 0.
• In the payload for setting the quota, instead of setting it to 0 * 1GB = 0, set it to 1. (The value is multiplied by 1GB because the ColdFront unit of measure we have settled on is GB, whereas Swift and RGW operate in Bytes)
• Make sure get_quota returns 0 still, for a value of 1 bytes. Which should be the case considering the int typecasting.
• Also, writing a test that exercises this behavior.

I asked @Milstein to manually set the RGW quota to 1 byte (not 1 gigabyte) and verify that it produces the desired outcome (inability to use object storage.)

@Milstein tested that setting the quota to 1 byte prevents people from upload files larger than 1 byte.

Until the code is in place and deployed setting the ColdFront quota to zero and then manually setting the RGW quota to 1 byte using the command line will prevent people from being billed for storage.

@Milstein is @knikolla's suggestion enough to close this and unblock https://github.com/nerc-project/operations/issues/304 ?
