Most notable changes include:

• introduction and integration of new Namespace type
• adding support for non-inclusion proofs for getting data by namespace

Also please note that we will deprecate writes on the REST gateway soon -- refer to this PR description for more information. This release disables these endpoints by default, but it is possible to re-enable them with a flag.

Another note: we skipped rc4 label, so celestia-node rc5 is compatible with latest celestia-app rc5 (it's just easier to remember).
