aws: Fix infinite loop when failing to untag resources

If AWS fails to untag a resource, it ends up going into an
infinite loop of querying tag client for resources and
retrying the untag process.

Trying a solution to retry the untagging of the resource
for a finite time and removing the tag client from the
list if it does not succeed.
