[Multitenant] S3 multitenancy: bucket implementation

[Arsnael]

Implement the bucket implementation for S3 blobstore multitenancy.

Derive a bucketname per tenant within S3BlobStoreDAO when using the bucket mode.

DoD: Integration tests

[vttranlina]

like what PG does

Can you help me give where code logic?
I checked the PGBlobStoreDAO, but don't see, even the pg table does not have a "domain" column,
I miss somewhere?

Can you help me give where code logic?

I asked myself the same question, as you can see in that other task => #5271 (comment)

So I aint sure either

Q: Theoretically we already support 1 bucket per domain, no?

[Arsnael]

I fail to see where in the code though, we have a bucket name column but I feel it's always default somehow. RLS is disabled on that table as well. But i might be wrong, in which case please point me to the right piece of code

I asked for S3 implementation instead.
