notification setting on a group should automatically be applied to all sub-groups/sub-projects
Description
(originally reported as https://salsa.debian.org/salsa/support/issues/54)
In Debian we're migrating to gitlab to host our packaging repositories.
for example take https://salsa.debian.org/python-team which contains 3 sub-groups: python modules packages (aka DPMT), python python applications packages (aka PAPT) and the interpreter packages.
setting the notification level at the python-team
level should be automatically applied recursively to its subgroups; and similarly, when you apply a given notification level to DPMT, that should apply automatically to all its subprojects.
currently to have to go in every single project in a sub-group and change the notification, which is unfeasible if you manage several tens of projects.
Proposal
please make the notification on a higher "hierarchical" level apply to the sub-items too
