Review Comment:
Initially I remember we had added it because we plan to find multiple
datasets and the return type also being a List. The current implementation
however only caters to one matching dataset based on the `dbname` and
`tableName`. In light to support a list of matching datasets taking in may be a
`list of (dname, tableName)`... we added the size. Either way, we can remove it
for now and add it later when we support multiple `IcebergDataset`. I have kept
it as is in my latest commit though... but can get rid of it!

Review Comment:
Makes sense to have separate catalog class keys for src and dest... to keep
it flexible and agnostic. I have added two props... each for src and dest and
fallback to a default value if either of them are unspecified.
