Description of problem:
The cluster-image-registry-operator, when a request to the associated S3 storage fails with any reason, it leaves the connection created for that request open.
This blocks a port. When this keeps happening, no more ports gets available for new connections and it gives the following error -
E1019 06:23:08.149459 90 controller.go:311] unable to sync: unable to sync storage configuration: RequestError: send request failed
caused by: Head https://<s3_storage>: dial tcp <ip_address>:443: connect: cannot assign requested address, requeuing
