Description

As discussed with dawidwys, the original purpose to separate ReadableCatalog and ReadableWritableCatalog is to isolate access to metadata. However, we believe access control and authorization is orthogonal to design of catalog APIs and should be of a different effort.

Thus, we propose to merge ReadableCatalog and ReadableWritableCatalog to simplify the design.
