As part of WT-14909, we will extend test_layered.* tests with verify through the wttest teardown. However, we have excluded test_layered(57|41|21|22|17) tests. These tests are configured with follower role and require further special handling.

Followers missing stable tables prior to picking up their first checkpoint will fail verification with "verify(layered): stable table verification failed : No such file or directory". This is an okay transient state to have and therefore we should allow this state to pass verification. We should be able to account for leader/follower role. We cannot rely on the following as role is currently hardcoded as leader: and is only  used/updated when the disagg hook (which is incompatible with layered tests and other disagg tests) is in use.

disagg = self.getDisaggParameters(} <--- only used for disagg hook
role = disagg.role 

try:
    self.verifyUntilSuccess(session, uri)
except wiredtiger.WiredTigerError as e:
    if str(e) == os.strerror(errno.ENOENT) and role == 'follower':
        pass

Secondly, there are cases where tests (i.e. test_layered(17|22)) with follower configurations stall indefinitely.

Definition of done:

• Check for leader/follower configurations through other means.
• Extend the currently excluded layered tests with verification and remove them from the exclusion list.
• Account for followers missing stable constituents failing with ENOENT. This is an okay transient state to have.
