[connection] replace .running_dbapi_query with .hooks_in_progress
The thing was badly named.
It tries to help distinguish between queries issued
directly by the programmer (e.g in the views: cnx.execute(...))
from queries issued from the hooks, operations ... or even
the repository or the native source objects.
It worked heuristically being associated with
the security being disabled.
We provide a better name and an implementation distinct from
the security management methods.
Related to #3933480.
