extends fix of CAMEL-21713: endpoint url override to aws-secret-manager

[JiriOndrusek]

follows #17052

The override endpoint url is missing also for CloudTrailClient.
The localstack cloudtrail lookup is not implemented yet, therefore endpoint url override cannot be used now in this case. But I think that it is better to have the code prepared for the future.

is this something that is good to backport to 4.8.x branch ?

It's not required for backport to 4.8.x from my POV. Very simple workaround is to add parameters with credentials with "fake" values.
On the other hand the fix is so small, that it should be save to backport and it should make users happier when using azure-key-vault with identity.

the change is for testing only, therefore there is no need to backport.
