* all namespace-methods deprecated and replicated with keyspace

* introduce update_db_keyspace parameter, deprecate update_db_namespace + tests

* fixed the deprecation of 'namespace' when it is a property

* fix/simplify stacklevel logic for deprecation utilities

* first sweep to rename internal variables

* second sweep to rename internal variables

* exceptions, constants and a few renames in tests

* DatabaseInfo and CollectionInfo double-attributes

* keyspace as parameter to all methods, with namespace as deprecated alias

* all 'namespace=' renamed

* swept/cleaned docstrings and stray references

+APICommander logs warnings received from the Data API
 Full removal of "core library" from the current API:
     - DevOps API accessed through APICommander everywhere
     - Admin objects use APICommander consistently
     - [Async]Database and [Async]Collection directly use APICommander
     - Cursor library uses APICommander directly
     - Core library imports triggers a submodule-wide deprecation warning
