Prevent CI to be run for whole collection (#728) (#732)

[PR #728/6d0e2948 backport][stable-3] Prevent CI to be run for whole collection

This is a backport of PR #728 as merged into main (6d0e294).
SUMMARY

Add a fake integration suite including an aliases file listing every module name with missing integration tests.
This fake suite is necessary for the new CI ansible-test-splitter behaviour. If one of the modules (listed in the aliases file) without a test suite is modified, the CI is run for the entire collection since the ansible-test-splitter won't find any target match. This fake integration suite helps handle this situation by avoiding running the CI for the whole collection. Furthermore, since the modules listed in the aliases file are marked as disabled, tests are automatically skipped.
